What is 4 square root 7^3 in exponential form?
Gnesinka [82]

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}}
