Answer 1

I’ve answered all your questions on your other post by the way and one of this persons answers isn’t correct. I’ve also given a detailed explanation for each one

Answer 2

1.8/125 cm³

2. 13

3a. x³-17

3b. 3x-5

5. A) Power

Explanation:

1. (2/5)³= 2/5 * 2/5 * 2/5

= 4/25 *2/5

=8/125

2. b³+(10-a)

= (2)³ + (10-5)

=(2*2*2) + (5)

= 8 + 5

= 13

3a. a number cubed = x³

seventeen less than = -17

3b. three times a number = 3x

five = 5

5. product is when two values are multiplied (13 and 3+x)
