Answer 2

To solve the expression, let's simplify each part step by step:

Step 1: Simplify the radicals. √40 = √(4 * 10) = √4 * √10 = 2 * √10

Step 2: Simplify the 4th root. 4√√40 = 4√(2 * √10) = 4√2 * 4√(√10) = 4√2 * 4√(2 * √2) = 4√2 * 4 * √2 = 4√2 * 4√2 = 4 * 4 = 16

Step 3: Replace the values in the expression. 4√11 - √40 * 4√√40 + 11 = 4√11 - 2 * 16 + 11

Step 4: Simplify further. 4√11 - 32 + 11 = 4√11 - 21

So, the simplified expression is 4√11 - 21.
