Evaluate Using Scientific Notation (1.4310^15)÷1.0910^12

$1.43 \cdot 10^{15} \div 1.09 \cdot 10^{12}$

Step 1

Divide using scientific notation.

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

$(\frac{1.43}{1.09}) (\frac{10^{15}}{1}) \cdot 10^{12}$

Divide $1.43$ by $1.09$ .

$1.3119266 \frac{10^{15}}{1} \cdot 10^{12}$

Divide $10^{15}$ by $1$ .

$1.3119266 \cdot 10^{15} \cdot 10^{12}$

Step 2

Multiply $10^{15}$ by $10^{12}$ by adding the exponents.

Move $10^{12}$ .

$1.3119266 \cdot (10^{12} \cdot 10^{15})$

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$1.3119266 \cdot 10^{12 + 15}$

Add $12$ and $15$ .

$1.3119266 \cdot 10^{27}$
