6^4

Answer 5

which by the rule of exponentes: a^n/a^m=a^n-m, is x=6^5

Answer 6

two powers with same base have the same ^? too.

Answer 7

which is then: x=7776

Answer 8

it is not 6/5 because it is not 6^4x=6^9 but 6^(4x)=6^9

Answer 9

oh, well, i mean there weren't any parentheses, so it could be interpreted any way

ok i understand the rule of exponents but how can it be 7776

Answer 11

well, what is the problem? is it like this 6^4*x=6^9 or is it 6^(4x)=6^9?
