Thank you.

I have another log question. Cannot use calculator.

So, should I add or subtract first?

if I add I get which I can't figure out how to simplify any further. If I subtract , what would I do next?

Thanks for helping. - Apr 14th 2010, 02:53 AMdesiderius1
Ah, ok I figured it out.

Log B2 {logB4 (2) +logB4(8) }^3

Work inside brackets first

!/2 +logB4(16/2)=1/2 +2 -1/2 = 2 2^3=8

Now you have logB2(8)=3
