Question

Evaluate using logarithm table: $\frac{28.45\times \sqrt[3]{30.3254}}{32.43\times \sqrt[5]{50.3046}}$

• A. $0.7666$
• B. $0.7656$
• C. $0.5686$
• D. $0.2936$

Answer 1

The correct option is B $0.7656$

Let $y=\frac{28.45\times \sqrt[3]{3.3254}}{32.43\times \sqrt[3]{3.3046}}$

$\ln y=\ln 28.45+\ln \sqrt[3]{3.3254}-(\ln 32.43+\ln \sqrt[5]{5.3046})\ln y=\ln 25.45+\frac{1}{3}\ln .3245-\ln 32.43-\frac{1}{5}\ln .4046\ln y=3.236+(-.375)-3.479-(-.237)\ln y=-.381$

$y=$ anti $\ln (-.381)$

$y=.7656$

So, option B is correct.
