Question

Solve

$\frac{5.6\times {10}^6}{{3\times 10}^{-4}(1.76\times {10}^{11})}$

Answer 1

$r=\frac{5.6\times {10}^6}{3\times {10}^{-4}(1.76\times {10}^{11})}$

$=\frac{5.6\times {10}^6\times {10}^4}{3\times 1.76\times {10}^{11}}$

$=\frac{5.6\times {10}^{10}}{3\times 1.76\times {10}^{11}}$

$=\frac{5.6}{3\times 1.76\times 10}$

$=\frac{5.6}{52.8}$

=0.106(approx)
