Question

useing logarithm table find the value of 3[(31.42 × 7.192) /0.236)² ]​

Answer 1

$x = 3 [ \frac{(31.42) \times (7.192)}{ {(0.236)}^{2} } ]$

Taking common log on both the sides:

$lg(x) = lg(3) + lg(31.42) + lg(7.192) - 2 \: lg(0.236)$

$lg(x) \approx 0.4771 + 1.4972+ 0.8568 + 2(0.6271)$

$lg(x) \approx4.0853$

$antilog _{10} ( log_{10}(x) ) \approx {10}^{4.0853}$

Hence,

$x \approx12170.264$

Real, value :

$x \approx 12171.7523$
