Evaluate Using Scientific Notation (210^2)(210^3)

$(2 \cdot 10^{2}) (2 \cdot 10^{3})$

Step 1

Multiply $2$ by $2$ .

$4 (10^{2} \cdot 10^{3})$

Step 2

Multiply $10^{2}$ by $10^{3}$ by adding the exponents.

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

$4 \cdot 10^{2 + 3}$

Add $2$ and $3$ .

$4 \cdot 10^{5}$
