\left(6x10^2\right)\div \left(3x10^{-5}\right)

Trava [24]

Answer:

$\frac{6\times 10^2}{3\times 10^{-5}}$ = 2 x 10⁷

Step-by-step explanation:

Given expression is $\frac{6\times 10^2}{3\times 10^{-5}}$

The given expression is simplified as follows;

$\frac{6\times 10^2}{3\times 10^{-5}} = (\frac{6}{3} )\times 10^{2-(-5)}\\\\(\frac{6}{3} )\times 10^{2-(-5)} = (\frac{6}{3} )\times 10^{2+5}\\\\(\frac{6}{3} )\times 10^{2+5} = 2 \ \times \ 10^7$

Therefore, the result of the given expression is 2 x 10⁷
