Perform the indicated computation . Write the answer in scientific notation. (15times 10^5)/(3times 10^-2) 5times 10^7 10times 10^7 10times 10^3 5times 10^3

1. Simplify the division<br /> Divide $15 \times 10^5$ by $3 \times 10^{-2}$ using $\frac{a \times 10^m}{b \times 10^n} = \frac{a}{b} \times 10^{m-n}$.<br /> $\frac{15}{3} \times 10^{5 - (-2)} = 5 \times 10^{7}$.<br /><br />2. Multiply with remaining terms<br /> Multiply $5 \times 10^{7}$, $10 \times 10^{7}$, $10 \times 10^{3}$, and $5 \times 10^{3}$.<br /> $(5 \times 10^{7}) \times (10 \times 10^{7}) \times (10 \times 10^{3}) \times (5 \times 10^{3}) = 5 \times 10^{7} \times 10 \times 10^{7} \times 10 \times 10^{3} \times 5 \times 10^{3}$.<br /><br />3. Combine powers of ten<br /> Combine powers: $5 \times 10^{7} \times 10^{7} \times 10^{3} \times 10^{3} = 5 \times 5 \times 10^{7+7+3+3}$.<br /><br />4. Calculate final result<br /> $25 \times 10^{20}$.<br /><br />5. Convert to scientific notation<br /> Scientific notation: $2.5 \times 10^{21}$.
