# Simplify the following: 4√28 ÷ 3√7 ÷ ∛7

**Solution:**

Given, the expression is 4√28 ÷ 3√7 ÷ ∛7

We have to simplify the expression.

4√28 = 4(√7×4)

= 4(2√7)

= 8√7

4√28 ÷ 3√7 = 8√7 / 3√7

= 8/3

\(\sqrt[3]{7}=(7)^{\frac{1}{3}}\)

4√28 ÷ 3√7 ÷ \(\sqrt[3]{7}\) = 8/3 ÷ \((7)^{\frac{1}{3}}\)

= 8/(3\((7)^{\frac{1}{3}}\))

= 8/(3 ∛7)

Therefore, 4√28 ÷ 3√7 ÷ ∛7 = 8/(3 ∛7)
