64-81=17?

OpenStudy (chosenmatt):

thanks!

OpenStudy (anonymous):

3x3x3x3=81 4x4x4=64

Nnesha (nnesha):

nope 81-64 = 17 if you do 64 - 81 = -17 bec 81 is bigger and have negative sign

OpenStudy (anonymous):

np

Nnesha (nnesha):

so its 81 -64 = 17 :) like Thefaceless said :)

OpenStudy (chosenmatt):

What is 144 written as a power of a number?

OpenStudy (chosenmatt):

@Nnesha @Thefaceless

OpenStudy (chosenmatt):

is it 12^2?

Nnesha (nnesha):

yes can be :)

OpenStudy (anonymous):

yes because 12x12=144 to make life easier, when we have two of the same number being multiplied we can write it in exponential form: 12x12=12^2=144
