Question

20√3+5√27-2√12 and
find simplest form of √125 and √80​

Answer 1

Step-by-step explanation:

$20 \sqrt{3} + 5 \sqrt{27} - 2 \sqrt{12} \\ = 20 \sqrt{3} + 15 \sqrt{3} - 4 \sqrt{3} \\ = 35 \sqrt{3} - 4 \sqrt{3} \\ = 31 \sqrt{3}$

and,

$\sqrt{125} \\ = \sqrt{5 \times 5 \times 5} \\ = 5 \sqrt{5}$

and,

$\sqrt{80} \\ = \sqrt{2 \times 5 \times 2 \times 2 \times 2} \\ = 2 \times 2 \sqrt{5} \\ = 4 \sqrt{5}$
