Answer 2

Let's simplify the expression step by step:

1. Simplify the square roots:

   • √64 = 8
   • √81 = 9
   • √32 = √(16 * 2) = 4√2

2. Plug in the values:

   • (3√64 + 4√81) * 5√32
   • (3 * 8 + 4 * 9) * 5 * 4√2
   • (24 + 36) * 20√2
   • 60 * 20√2

3. Multiply the numbers:

   • 60 * 20√2 = 1200√2

So, (3√64 + 4√81) * 5√32 simplifies to 1200√2.
