Evaluate Using Scientific Notation (4.510^-4)/(510^-7)

$\frac{4.5 \cdot 10^{- 4}}{5 \cdot 10^{- 7}}$

Step 1

Divide using scientific notation.

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

$(\frac{4.5}{5}) (\frac{10^{- 4}}{10^{- 7}})$

Divide $4.5$ by $5$ .

$0.9 \frac{10^{- 4}}{10^{- 7}}$

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

$0.9 \cdot 10^{- 4 - 7 \cdot - 1}$

Multiply $- 7$ by $- 1$ .

$0.9 \cdot 10^{- 4 + 7}$

Add $- 4$ and $7$ .

$0.9 \cdot 10^{3}$

Step 2

Move the decimal point in $0.9$ to the right by $1$ place and decrease the power of $10^{3}$ by $1$ .

$9 \cdot 10^{2}$
