Question

simplify 3√3+2√27+7/√3​

Answer 1

Answer:

$3 \sqrt{3} + 2 \sqrt{27} + 7 \sqrt{3} \\ = 3 \sqrt{3} + 2 \sqrt{3 \times 3 \times 3} + 7 \sqrt{3} \\ = 3 \sqrt{3} + 2 \sqrt{ {3}^{2} \times 3 } + 7 \sqrt{3} \\ = 3 \sqrt{3} + (2 \times 3 \sqrt{3} ) + 7 \sqrt{3} \\ = 3 \sqrt{3} + 6 \sqrt{3} + 7 \sqrt{3} \\ = (3 + 6 + 7) \sqrt{3} \\ = 16 \sqrt{3}$

Answer 2

Answer:

$19.63$

Explanation:

$given \: solution \: \\ = > 3 \sqrt{3} + 2 \sqrt{27} + \frac{7}{ \sqrt{3} } \\ \\ = > 3 \sqrt{3} + 2 \sqrt{3 \times 3 \times 3} + \frac{7}{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} } \\ = > \: rationalising \: the \: denominator \: \\ = > 3 \sqrt{3} + 6 \sqrt{3} + \frac{7 \sqrt{3} }{3} \\ = > |3 + 6 + \frac{7}{3} | \times \sqrt{3} \\ = > \frac{34}{3} \times \sqrt{3} = 19.63$
