(I have two questions)
1. Solve for x without a calculator:
log3(x^2)=2log3(4)4log3(5)
This is what I have so far:
2log3(x)=log3(4^2)log3(5^4)
2log3(x)=log3(16/625)
...and now I'm stuck.
2. Simplify:
2log4(9)2log3 <how do you simplify with different bases?
Thanks!

Reiny,
from
2log3(x)=log3(16/625)
log3 (x^2) = log3 (16/625
so x^2 = 16/625
x = √(16/625) = 4/25
