29. 5 ^ (x-1) = 9 --> log 5 ^ (x-1) = log 9 --> (x-1) log 5 = log 9 --> x-1 = log 9 / log 5 | x = (log 9 / log 5) -1 Use your calculator. btw, log base is 10 for all.

oops haha sorry [tag]heng:5396bc2b1cc1f[/tag]. The working would be the same until second last step of ShamSuiisses ans. Cont' from his working,[ieqn]\frac{q^{1/2}}{3q}=\frac{p^{2}}{p}\\ \frac{q^{1/2}}{q}=3p\\ q^{-1/2}=3p\\ (q^{-1/2})^{-2}=(3p)^{-2}\\ q=\frac{1}{9p^{2}}[/ieqn]
