Question

Using quotient law simplify $\frac{15a^2}{3a^5}$

• A. 3a³
• B. 5a⁵
• C. 5/a³
• D. 5/a⁵

Answer 1

The correct option is C

5/a³

Using quotient law, we know that $\frac{a^m}{a^n}=\frac{1}{a^{n-m}}$if $m<n$

Therefore,$\frac{15a^2}{3a^5}=\frac{15a^2}{3a^5}$

=$\frac{5}{a^{5-2}}$

=$\frac{5}{a^3}$
