Evaluate Using Scientific Notation (710^7)/(210^5)

$\frac{7 \cdot 10^{7}}{2 \cdot 10^{5}}$

Step 1

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

$(\frac{7}{2}) (\frac{10^{7}}{10^{5}})$

Step 2

Divide $7$ by $2$ .

$3.5 \frac{10^{7}}{10^{5}}$

Step 3

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

$3.5 \cdot 10^{7 + 5 \cdot - 1}$

Step 4

Multiply $5$ by $- 1$ .

$3.5 \cdot 10^{7 - 5}$

Step 5

Subtract $5$ from $7$ .

$3.5 \cdot 10^{2}$
