# How do you divide (6.12xx10^4) / (3xx10^2)?

Apr 4, 2015

The answer is $2 \times {10}^{2}$.

Divide the coefficients.

$\frac{6.12}{3} = 2.04$

Subtract the exponent in the denominator from the exponent in the numerator.

${10}^{4 - 2} = {10}^{2}$

The calculated answer is $2.04 \times {10}^{2}$. Round to $2 \times {10}^{2}$ due to $3 \times {10}^{2}$ having one significant figure.
