# Simplify the following: 3√3 + 2√27 + 7/√3

**Solution:**

Given, the expression is 3√3 + 2√27 + 7/√3

We have to simplify the expression.

2√27 = 2√9 × 3

= 2(3√3)

= 6√3

Rationalising the denominator,

7/√3 = (7/√3) × (√3/√3)

= 7√3/3

3√3 + 2√27 + 7/√3 = 3√3 + 6√3 + 7√3/3

= √3(3 + 6 + 7/3)

= √3(9 + 7/3)

= √3(27+7)/3

= 34√3/3

Therefore, 3√3 + 2√27 + 7/√3 = 34√3/3
