Write \(\displaystyle \frac{3}{2}\) as a power with a base of 10.
We have: \(\displaystyle \:10^x\;=\;1.5\)
Take logs of both sides (base 10): \(\displaystyle \:\log\left(10^x\right) \;= \;\log(1.5)\)
Then we have: \(\displaystyle \:x\cdot\log(10) \;= \;\log(1.5)\)
Since \(\displaystyle \,\log(10)\,=\,1\), we have: \(\displaystyle \:x\;=\;\log(1.5) \;= \;0.176091259...\)
Therefore: \(\displaystyle \L\:\frac{3}{2} \:\approx\:10^{0.176}\)

. . \(\displaystyle \begin{array}{cccc}10^{0.1760} & = & 1.499684836 \\ \; \\ \; \\10^{0.1761} & = & 1.500030190\end{array}\) . . . not bad!
