Which expression is equivalent to<br> min<br> pg?<br> mºn<br> po<br> m2
ziro4ka [17]

Answer:

The expression equivalent to (\frac{m^{5}n}{pq^{2}})^{4} is  \frac{m^{20}n^{4}}{p^{4}q^{8}} ⇒ C

Step-by-step explanation:

Let us use the exponent rule (a^{m})^{n} = a^{m.n}

∵ The expression  is (\frac{m^{5}n}{pq^{2}})^{4}

→ By using the rule above multiply the power of each letter by 4

∵ (m^{5})^{4} = m^{20}

∵ (n^{1})^{4} = n^{4}

∵  (p^{1})^{4} = p^{4}

∵ (q^{2})^{4} = q^{8}

→ Substitute them in the expression above

∴ (\frac{m^{5}n}{pq^{2}})^{4} = \frac{m^{20}n^{4}}{p^{4}q^{8}}

∴ The expression equivalent to (\frac{m^{5}n}{pq^{2}})^{4} is  \frac{m^{20}n^{4}}{p^{4}q^{8}}
