Video Solution

Solution Steps

00:00 Simplify the following expression
00:03 We'll simplify in 2 different ways, first we'll solve the parentheses
00:08 This is one way
00:12 Now let's see the second way of simplification
00:16 In order to open parentheses with an exponent over multiplication
00:20 We raise each factor to the power
00:24 We'll use this formula in our exercise
00:30 In multiplication, the order of factors doesn't matter
00:35 Therefore, both expressions are equal
00:38 We'll use this formula in our exercise and switch the factors
00:45 Again we'll use the formula in order to simplify the power of multiplication
00:51 This is the solution to the problem

Step-by-Step Solution

To solve this problem, we'll apply the power of a product rule to the expression (10×3)4(10 \times 3)^4.

  • Step 1: Identify the expression.
    The given expression is (10×3)4(10 \times 3)^4.

  • Step 2: Apply the power of a product law.
    According to the rule, (a×b)n=an×bn(a \times b)^n = a^n \times b^n, our expression becomes:
    (10×3)4=104×34(10 \times 3)^4 = 10^4 \times 3^4.

  • Step 3: Evaluate the choices:
    - First choice: 34×1043^4 \times 10^4
    Rearranging terms, this is equivalent to 104×3410^4 \times 3^4. Therefore, it matches our transformed expression.
    - Second choice: 30430^4
    Since 30=10×330 = 10 \times 3, (10×3)4=304(10 \times 3)^4 = 30^4. This simplifies to the same expression.
    - Third choice: 104×3410^4 \times 3^4

    Therefore, the solution is that all answers are correct.
