Video Solution

Solution Steps

00:06 Let's simplify this math problem together.
00:10 To begin, open the parentheses by using multiplication and the outside exponent.
00:15 Raise each part inside the parentheses to the power.
00:19 Make sure every factor is raised to the power.
00:23 And that's how you find the solution!

Step-by-Step Solution

To solve the expression (2×x)2(2 \times x)^2, we'll follow these steps:

  • Step 1: Identify the base of the exponent, which is the product 2×x2 \times x.
  • Step 2: Apply the Power of a Product rule, which states that (ab)n=an×bn(ab)^n = a^n \times b^n.
  • Step 3: Distribute the exponent to both factors within the parentheses:

(2×x)2=22×x2(2 \times x)^2 = 2^2 \times x^2

Calculating 222^2 gives:

22=42^2 = 4

So, the expression simplifies to:

4×x24 \times x^2

Therefore, the correct expression is 22×x22^2 \times x^2.

This corresponds to Choice 2.

Answer

22×x2 2^2\times x^2
