$\frac{- 9 \cdot 10^{7}}{- 2 \cdot 10^{- 8}}$

Step 1

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

$(\frac{- 9}{- 2}) (\frac{10^{7}}{10^{- 8}})$

Step 2

Divide $- 9$ by $- 2$ .

$4.5 \frac{10^{7}}{10^{- 8}}$

Step 3

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

$4.5 \cdot 10^{7 - 8 \cdot - 1}$

Step 4

Multiply $- 8$ by $- 1$ .

$4.5 \cdot 10^{7 + 8}$

Step 5

Add $7$ and $8$ .

$4.5 \cdot 10^{15}$
