(7^(7)*7^(0))/(7^(5)*7^(2))

no not all of them.

step-by-step explanation:

some of them have a square base.

i think the answer is b.

step-by-step explanation:

not 100% sure though.

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
