Answer:
18√2
Explanation:
18 = 9*2
Therefore:
√18 = √9 * √2 = 3√2 ........> I
162 = 81*2
Therefore:
√162 = √81 * √2 = 9√2 ...........> II
The given expression is:
2√18 + 3√2 + √162
Substitute with I and II and evaluate the result as follows:
2√18 + 3√2 + √162
2*3√2 + 3√2 + 9√2
6√2 + 3√2 + 9√2
= (6+3+9)√2
= 18√2
Hope this helps :)
