Evaluate Using Scientific Notation (1.410^-8)/(3.510^-13)

$\frac{1.4 \cdot 10^{- 8}}{3.5 \cdot 10^{- 13}}$

Divide using scientific notation.

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

$(\frac{1.4}{3.5}) (\frac{10^{- 8}}{10^{- 13}})$

Divide $1.4$ by $3.5$ .

$0.4 \frac{10^{- 8}}{10^{- 13}}$

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

$0.4 \cdot 10^{- 8 - 13 \cdot - 1}$

Multiply $- 13$ by $- 1$ .

$0.4 \cdot 10^{- 8 + 13}$

Add $- 8$ and $13$ .

$0.4 \cdot 10^{5}$

Write $0.4 \cdot 10^{5}$ in proper scientific notation.

$4 \cdot 10^{4}$
