Answer:

Given the radical form: $4\sqrt{7^3}$

Use the exponent rules:

$\sqrt[n]{a^m} = (a^m)^{\frac{1}{n}} = a^{\frac{m}{n}}$

we can write $\sqrt{7^3}$ as:

$\sqrt{7^3} = (7^3)^{\frac{1}{2}} = 7^{\frac{3}{2}}$

then;

$4\sqrt{7^3}$ = $4 \cdot 7^{\frac{3}{2}}$

Therefore, $4\sqrt{7^3}$ in exponential form is $4 \cdot 7^{\frac{3}{2}}$
