Video Solution

Step-by-Step Solution

To solve this problem, we will proceed with the following steps:

  • Identify the expression structure.
  • Apply the power of a power rule for exponents.
  • Simplify the expression.

Now, let's work through each step in detail:

Step 1: Identify the expression structure.
We have the expression (103)3(10^3)^3. This indicates a power of a power where the base is 10, the inner exponent is 3, and the entire expression is raised to another power of 3.

Step 2: Apply the power of a power rule.
The rule states (am)n=am×n(a^m)^n = a^{m \times n}. Applying this to our specific expression gives us:

(103)3=103×3\left(10^3\right)^3 = 10^{3 \times 3}

Step 3: Perform the multiplication in the exponent.
Calculating 3×33 \times 3, we get 99. Thus, the expression simplifies to:

10910^9

Therefore, the solution to the problem is:

103×3\boxed{10^{3 \times 3}}

Examining the provided choices:

  • Choice 1: 103+310^{3+3} - Incorrect, because it uses addition instead of multiplication.
  • Choice 2: 103×310^{3 \times 3} - Correct, as it matches our derived expression.
  • Choice 3: 103310^{\frac{3}{3}} - Incorrect, because it uses division instead of multiplication.
  • Choice 4: 103310^{3-3} - Incorrect, because it uses subtraction instead of multiplication.

The correct answer is 103×310^{3 \times 3}, which is represented by Choice 2.

Answer

103×3 10^{3\times3}
