OpenStudy (adajiamcneal):
that is 6
OpenStudy (anonymous):
Which is equal to 3^3 • 3^5?
OpenStudy (triciaal):
b^-3 = 1/b^3 = 1/216
b^3 = 216 take the cube root of each side
(b^3)^1/3 = (216)^1/3
yes b = 6
OpenStudy (anonymous):
3^8 ?
OpenStudy (adajiamcneal):
yeah I was actually solving it pero that is right too haha

12^5^3=12^?
this is not 12^8 it would be 12^15
OpenStudy (triciaal):
6^-8/6^-2 = 6^(-8--2) = 6^(-8 + 2) = 6^-6 = C
