Math Problem Statement

Simplify the expression 2√2 + √32.

Solution

Let's solve the given expression step by step:

Expression:

22+322\sqrt{2} + \sqrt{32}


Step 1: Simplify 32\sqrt{32}

The number 32 can be written as 16×216 \times 2. Using the square root property ab=ab\sqrt{a \cdot b} = \sqrt{a} \cdot \sqrt{b}, we get: 32=162=162=42.\sqrt{32} = \sqrt{16 \cdot 2} = \sqrt{16} \cdot \sqrt{2} = 4\sqrt{2}.

So, the expression becomes: 22+42.2\sqrt{2} + 4\sqrt{2}.


Step 2: Combine like terms

Both terms have 2\sqrt{2} as a common factor. Combine them: 22+42=(2+4)2=62.2\sqrt{2} + 4\sqrt{2} = (2 + 4)\sqrt{2} = 6\sqrt{2}.


Final Answer:

626\sqrt{2}
