Evaluate Using Scientific Notation (910^8)/(210^5)

$\frac{9 \cdot 10^{8}}{2 \cdot 10^{5}}$

Step 1

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

$(\frac{9}{2}) (\frac{10^{8}}{10^{5}})$

Step 2

Divide $9$ by $2$ .

$4.5 \frac{10^{8}}{10^{5}}$

Step 3

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

$4.5 \cdot 10^{8 + 5 \cdot - 1}$

Step 4

Multiply $5$ by $- 1$ .

$4.5 \cdot 10^{8 - 5}$

Step 5

Subtract $5$ from $8$ .

$4.5 \cdot 10^{3}$
