$\frac{8.4 \cdot 10^{6}}{2 \cdot 10^{- 2}}$

Step 1

Group coefficients together and exponents together to divide numbers in scientific notation.

$(\frac{8.4}{2}) (\frac{10^{6}}{10^{- 2}})$

Step 2

Divide $8.4$ by $2$ .

$4.2 \frac{10^{6}}{10^{- 2}}$

Step 3

Subtract the exponent from the denominator from the exponent of the numerator for the same base

$4.2 \cdot 10^{6 - 2 \cdot - 1}$

Step 4

Multiply $- 2$ by $- 1$ .

$4.2 \cdot 10^{6 + 2}$

Step 5

Add $6$ and $2$ .

$4.2 \cdot 10^{8}$
