Question 140503: can you help me solve this? log of x to base 2, quantity squared, minus 12 log of x to base 2 =-32, solve for x
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! log of x to base 2, quantity squared, minus 12 log of x to base 2 =-32, solve for x
--------------------
(log2 x)^2 - 12*log2 x + 32 = 0
Keep the base in mind, then factor to get:
(log x - 4)(logx - 8) = 0
log2 x = 4 or log2 x = 8
x = 2^4 or x = 2^8
x = 16 or x = 256
