1
2
. Find x.
(a) 4 (b)
1
2
(c) 1 (d) 2

3. Exponents and Logarithms
log9 (3log2 (1 + log3 (1 + 2log2x)) =
1
2
3log2 (1 + log3 (1 + 2log2x)) = 91/2 = 3
log2 (1 + log3 (1 + 2log2x) = 1
1 + log3 (1 + 2log2x) = 2
log3 (1 + 2log2x) = 1
log9 (3log2 (1 + log3 (1 + 2log2x))) =
1
2
. Find x.

4. Exponents and Logarithms
