Question

$(5mn^3)^{3}$
​

Answer 1

Answer:

$125m {}^{3}n {}^{6}$

Step-by-step explanation:

Since

$a {}^{b} \times a {}^{c} = a {}^{b + c}$

$(5mn {}^{3} ) {}^{3} = (5) {}^{3}(m) {}^{3} (n {}^{3}) {}^{3} = 125m {}^{3}n {}^{3 + 3} = 125m {}^{3}n {}^{6}$

Hope this helps :) ❤❤❤

Answer 2

Answer:

$125m^3n^9$

Step-by-step explanation:

$(a*b)^n=a^nb^n\\\\(5mn^3)^3=5^3m^3(n^3)^3\\\\125m^3(n^3)^3\\\\(a^b)^c=a^{bc}\\\\\rightarrow (n^3)^3=n^{3*3}=n^9\\\\\boxed{125m^3n^9}$
