2^5 =

2×2×2×2×2=32 because you multiply by 2 5 times which is 32

2×2=4 then 4×2=8 

8×2=16 and last 16×2=32

there are 5 2’s and all were multiplied 

9/10 -7/10=

The answer is 1/5 because you can subtract the numbers due to their denominator being the same

the first answer 2/10 but then you have to simplify to its lowest form

you get that by dividing it by 2 both top and bottom numbers

which is 1/5

62% of 11=

.62 ×11 which is 682

move the decimal back to its place

the answer is 6.82

65% of (x) = 81.25

Find the value of x

the value of x is 125 because

you first divide 81.25 by .65

then move the decimal
