Write the expression in simplest form

OpenStudy (andrewthecookie):

Haley :D

OpenStudy (haleyelizabeth2017):

\[(8a^{-3})^{\frac{ -2 }{ 3 }}\]

OpenStudy (haleyelizabeth2017):

I have to show steps :(

OpenStudy (andrewthecookie):

This is order of operations

OpenStudy (andrewthecookie):

You must do the work in Parentheisis first

OpenStudy (haleyelizabeth2017):

I don't remember how to do it, sadly :(

OpenStudy (andrewthecookie):

Do you know the Order of Operation rules?

OpenStudy (haleyelizabeth2017):

I know how to do PEMDAS, but is that what I have to do? This is algebra 2....

OpenStudy (andrewthecookie):

Yep I think its PEMDAS

OpenStudy (aripotta):

you multiply the exponents

OpenStudy (haleyelizabeth2017):

okay one second...

OpenStudy (andrewthecookie):

Yep mupltity the exponents

OpenStudy (aripotta):

when you multiply -3 and -2/3 you get and exponent of 2

OpenStudy (aripotta):

so 8a^2

OpenStudy (haleyelizabeth2017):

okay because the -3 and -3 cancel just like fractions! :D

OpenStudy (andrewthecookie):

Exactly!

OpenStudy (haleyelizabeth2017):

is that all I do?

OpenStudy (aripotta):

that's all you can do. it's simplified

OpenStudy (andrewthecookie):

Yep

OpenStudy (haleyelizabeth2017):
