Math Problem Statement

sqrt(8) * (2sqrt(2) - 3sqrt(3)) =

Solution

Let's solve the expression:

8×(2233)\sqrt{8} \times (2\sqrt{2} - 3\sqrt{3})

Step 1: Simplify 8\sqrt{8}

We know that 8=4×2=22\sqrt{8} = \sqrt{4 \times 2} = 2\sqrt{2}.

So, the expression becomes:

22×(2233)2\sqrt{2} \times (2\sqrt{2} - 3\sqrt{3})

Step 2: Distribute 222\sqrt{2} across the terms in the parentheses

22×2222×332\sqrt{2} \times 2\sqrt{2} - 2\sqrt{2} \times 3\sqrt{3}

Step 3: Simplify each term

  1. 22×22=4×2=82\sqrt{2} \times 2\sqrt{2} = 4 \times 2 = 8
  2. 22×33=662\sqrt{2} \times 3\sqrt{3} = 6\sqrt{6}

So, the expression simplifies to:

8668 - 6\sqrt{6}

Thus, the simplified result is:

866\boxed{8 - 6\sqrt{6}}
