Evaluate fourth root of 40 fourth root of 250

$\sqrt[4]{40} \sqrt[4]{250}$

Step 1

Combine using the product rule for radicals.

$\sqrt[4]{40 \cdot 250}$

Step 2

Write the expression using exponents.

Multiply $40$ by $250$ .

$\sqrt[4]{10000}$

Rewrite $10000$ as $10^{4}$ .

$\sqrt[4]{10^{4}}$

Pull terms out from under the radical, assuming positive real numbers.

$10$
