Answer 1
Answer: remmember
(x^m)^n=x^(mn)

(x^-5)^n=2^-15

-5 times n=-15
divide both sides by -5
n=3

Answer:

Step-by-step explanation:

1) We would determine the cube root of 27 and find its square.

Cube root of 27 = 3

3² = 9

Solution = 9

2) 36³ = 46656

√36³ = √46656 = 216

3) we would find the 5th roof of - 243 and find its cube

5th root of - 243 = - 3

- 3³ = - 27

Solution = - 27

4) Looking at the expression, 40⅔, we can see that

a = 2

b = 3

c = 40

If i have 2 apple and get 3 more then lose 2 how many do i have left

Answers

You have 2 apples, get 3 more, and then lose 2 of them.

So, you HAVE 2 apples, and if you get 3 more, you can add it to the 2.
2 + 3 = 5

In total at the moment, you have 5 apples. Now, you lose 2 more. We can subtract that from our total number of apples.
5 - 2 = 3

We now know that you are left with 3 apples.
2 apples + 3 apples - 2 apples = 3 apples
