The exponent of 4 will apply to everything inside the brackets

OpenStudy (vshiroky):

Can you verify my answer?

OpenStudy (agent0smith):

What is it?

OpenStudy (vshiroky):

81a^4/16b^8

OpenStudy (agent0smith):

All good except, b^8 is not right

OpenStudy (vshiroky):

Why?

OpenStudy (agent0smith):

Bring the b^-3 into the denominator first, and it becomes b^3, right?

OpenStudy (agent0smith):

And b*b^3 = ...?

OpenStudy (vshiroky):

Would it be 16b^16

OpenStudy (agent0smith):

Yep!

OpenStudy (vshiroky):

Thank you!
