how do u solve for x?

log base 3 of x^2=2 log base 3 of 4- 4 log base 3 of 5?
 
rewrite the statement with the logs as per this
2 log base 3 of 4 = log base 3 of 4 ^ 2

then combine the 2 log statements on the right side (minus becomes a division in logs).
with a common log base 3 layout--drop this and solve for x

looks like it might be x=4/25
