Advanced Math Problems
Instructions: Work out the solutions to the problems beneath. Then check your answers, which are provided in the side by side section.
1) What is the equivalent of the following logarithmic function in exponential form? 4 = logthree81
2) What number is next in the sequence? 2, 4, sixteen . . .
iii) What is the square root of -5?
iv) What is x to the power of -6?
5) How many two letter combinations can be made from the alphabetic character set?:
H A N D Y
Answers to the Advanced Math Bug
1) 81 = 3 four
two) 256
3) an imaginary number
4) one/x vi
5) x
Solutions to the Advanced Math Bug
Solution i
ane) Here nosotros have the logarithmic office: 4 = log381
The above question is 1 of our trigonometric, logarithmic, or exponential office advanced math issues.
The logarithmic role x = logb y is the same as y = b x in exponential grade.
Recall 10 is for exponent and b is for base of operations number in the above formula.
So iv = log381 is the same equally 81 = 3 iv
Solution 2
2) What number is next in the sequence? 2, iv, 16 . . .
This is a series and sequences question.
For these problems, you have to discover the pattern that exists among of the numbers in the list provided.
In this series, each number is the previous number squared.
2 2 = 4
4 ii = 16
16 2 = 256
You may as well run across advanced math problems on how to calculate the nth item of a geometric sequence.
The first number in the sequence is represented by variable a and the multiplier (called the "mutual ratio") is represented past variable r.
The formula for computing the nth item in a geometric sequence is equally follows: ar(n-1)
Solution three
3) What is the square root of -25?
This is a question on imaginary numbers.
An imaginary number is the existent number solution to the problem multiplied by the imaginary unit of measurement i.
The square root of 25 is v, so our respond here is the imaginary number 5i.
Solution iv
iv) What is x to the power of -half dozen?
This is an advanced math trouble on manipulating square roots and exponents.
When you see a negative number as an exponent, y'all need to express the effect equally a fraction.
The fraction volition take ane in the numerator and the given term with a positive exponent in the denominator.
So, x -6 = 1/ten half dozen
Solution 5
v) You may have questions on combinations or permutations on the test.
Our question was: How many 2 alphabetic character combinations can be fabricated from the following five letter of the alphabet set? H A North D Y
Tip 1:
Retrieve that a combination, unlike a permutation, does not take into account the order of the items in the combination.
For example, the combination H A is considered the aforementioned every bit the combination A H.
To make up one's mind the number of combinations of S at a time that can be made from a set containing N items, you need this formula:
(N!) ÷ [(Northward − S)! × S!]
Think: S represents how many messages each combination should contain. Each combination will contain 2 letters in this exercise, so S = 2.
North represents total set up (H A Due north D Y in this example). So, N = 5 because there are v messages in the set.
So in the example above, S = 2 and Due north = 5
Hither is the formula again: (N!) ÷ [(N − S)! × S!]
Tip 2:
The exclamation point is a factorial.
For factorials, yous have to multiply the stated number by every number less than information technology. For example, 5! = 5 × 4 × iii × ii × one
At present substitute the values for Due south and N and acquit out the operation represented by the exclamation bespeak:
(5 × 4 × 3 × 2 × 1) ÷ [(5 − 2)! × two!] =
(five × iv × three × 2) ÷ [(3 × 2 × 1) × (ii × ane)] =
120 ÷ (six × ii) =
120 ÷ 12 = x
And then ten ii-letter combinations can be made from a five letter set.
Permuations
Permutations are like combinations, except permutations take into account the lodge of the items in each grouping.
For permutations of S at a time from a prepare containing N items, use the formula: Northward! ÷ (N – South)!

You may too come across questions like these on the advanced math bug department of your exam.
What ordered pair is a solution to the following system of equations?
x + y = 12
xy = 35
This is a systems of equations problem.
Questions in this skill prepare will include operations with imaginary numbers.
In the standard (x,y) airplane, what is the distance betwixt (3, 4) and (6, 2)?
HINT: If the problem is asking y'all nigh points on a airplane, for instance, y'all will need to utilise the distance formula.
This trouble is classified every bit geometry: graphs, coordinates, slope, lines, cones, and sets of points on a airplane.
So, a math question on this function of the test would be like to this 1.
Simplify the following:
This is a problem on simplifying rational expressions.
It is an case of a simplification problem, containing fractions inside fractions, like you will see on the test.
