What is the simplified form of the expression? 2sqrt18 - 5sqrt32
Morgarella [4.7K]

Answer

26√2

Step-by-step explanation:

The trick here lies in recognizing that both 18 and 32 have factors that are perfect squares:  18 = 2*9 and 32 = 2*16.  Therefore, we can write

2sqrt18 as 2√2√9, or 6√2, and 5sqrt32 as 5√2√16, or 20√2.

Then the original expression, in simplest form, is 6√2 + 20√2, or 26√2
