Find x if log\(_9\)x = 1.5

Find the value of log\(_{10}\)\(\frac{1}{40}\), given that log10\(_4\) = 0.6021

If log 2 = x, log 3 = y and log 7 = z, find, in terms of x, y and z, the value of log (\(\frac{28}{3}\))

Given that logx 64 = 3, evaluate x log\(_2\)8

Simplify 2log \(\frac{2}{5}\) - log\(\frac{72}{125}\) + log 9
