Question 68

By what number should $(-4{)}^5$ be divided so that the quotient may be equal to $(-4{)}^3$?

Answer 1

In order to find the number, which should divide $(-4{)}^5$ to get the quotient $(-4{)}^3$, we will divide $(-4{)}^5$ by $(-4{)}^3$.
Hence, required number $=\frac{(-4{)}^5}{(-4{)}^3}=(-4{)}^{5-3}=(-4{)}^2$.
