Answer 2

Let's break down the given expression step by step:

1. 5√32: The square root of 32 can be simplified as follows: √32 = √(16 × 2) = √16 × √2 = 4√2. Therefore, 5√32 = 5 × 4√2 = 20√2.

2. 4√81: The square root of 81 is 9 since 9 × 9 = 81. Therefore, 4√81 = 4 × 9 = 36.

3. 2³√-125: The cube root of -125 is -5 since -5 × -5 × -5 = -125. Therefore, 2³√-125 = 2 × (-5) = -10.

4. √64: The square root of 64 is 8 since 8 × 8 = 64.

Now, let's substitute the simplified values back into the original expression:

20√2 - 36 + (-10) + 8

Simplifying further:

20√2 - 36 - 10 + 8

Combining like terms:

20√2 - 38

Therefore, the simplified expression is 20√2 - 38.
