Answer 2

Let's simplify the expressions step by step:

1. 1/4 * √64 + √36 * √25:

First, calculate the square roots:

• √64 = 8
• √36 = 6
• √25 = 5

Now, substitute these values into the expression:

1/4 * 8 + 6 * 5

Now, perform the multiplications and additions:

2 + 30

The final result is 32.

2. 1/4 * √32 + 30√0.64 + √8:

First, calculate the square roots:

• √32 can be simplified further: √32 = √(16 * 2) = 4√2
• √0.64 = 0.8
• √8 = 2√2

Now, substitute these values into the expression:

1/4 * (4√2) + 30 * 0.8 + 2√2

Now, perform the multiplications and additions:

(1/4) * (4√2) = √2 30 * 0.8 = 24

So, the expression becomes:

√2 + 24 + 2√2

Now, combine like terms:

√2 + 2√2 + 24 = 3√2 + 24

The final result is 3√2 + 24.
