Step-by-step solution

To solve this problem, we'll apply the power of a power rule on the expression ((4×3)3)6((4 \times 3)^3)^6.

Here's how we proceed:

  • Step 1: Identify the expression
    The expression given is ((4×3)3)6 ((4 \times 3)^3)^6 .

  • Step 2: Apply the Power of a Power Rule
    According to the power of a power rule, (am)n=am×n(a^m)^n = a^{m \times n}.
    Therefore, ((4×3)3)6=(4×3)3×6((4 \times 3)^3)^6 = (4 \times 3)^{3 \times 6}.

  • Step 3: Calculate the Exponent Product
    Multiply the exponents: 3×6=183 \times 6 = 18.

  • Step 4: Simplify the Expression
    Thus, we have (4×3)18(4 \times 3)^{18}.

Therefore, the simplified expression is (4×3)18(4 \times 3)^{18}.

Comparing with the choices provided:

  • Choice 1: (4×3)2(4 \times 3)^2 - Incorrect.

  • Choice 2: (4×3)3(4 \times 3)^3 - Incorrect.

  • Choice 3: (4×3)18(4 \times 3)^{18} - Correct.

  • Choice 4: (4×3)3(4 \times 3)^{-3} - Incorrect.

Thus, the correct answer is: (4×3)18(4 \times 3)^{18}, which corresponds to choice 3

Final Answer

(4×3)18 \left(4\times3\right)^{18}

Key Points to Remember

Essential concepts to master this topic
  • Rule: When raising a power to a power, multiply the exponents together
  • Technique: For (am)n(a^m)^n, calculate am×na^{m \times n} like 3×6=183 \times 6 = 18
  • Check: Verify by expanding: ((4×3)3)6((4 \times 3)^3)^6 has 6 groups of 3 exponents ✓

Common Mistakes

Avoid these frequent errors
  • Adding exponents instead of multiplying them
    Don't add 3 + 6 = 9 to get (4×3)9(4 \times 3)^9! This treats the problem like multiplying powers with the same base, not raising a power to a power. Always multiply the exponents: 3 × 6 = 18 for the power of a power rule.

FAQ

Everything you need to know about this question

Why do I multiply the exponents instead of adding them?

+

The power of a power rule is different from multiplying powers! When you have (am)n(a^m)^n, you're taking ama^m and using it as a base n times, so you multiply: m×nm \times n.

What's the difference between this and am×ana^m \times a^n?

+

Great question! am×an=am+na^m \times a^n = a^{m+n} (you add exponents), but (am)n=am×n(a^m)^n = a^{m \times n} (you multiply exponents). The parentheses make all the difference!

Do I need to calculate 4×3=124 \times 3 = 12 first?

+

No! Keep it as (4×3)(4 \times 3) since that's what the answer choices show. The key is applying the power rule to get the correct exponent: 18.

How can I remember when to multiply vs add exponents?

+
  • Multiply exponents: When you see (something)power(something)^{power} raised to another power
  • Add exponents: When multiplying the same base with different powers

What if I calculated 121812^{18} - is that wrong?

+

Mathematically, (4×3)18=1218(4 \times 3)^{18} = 12^{18} is correct! But the question asks for the corresponding expression in the same format as the choices, so (4×3)18(4 \times 3)^{18} is the answer they want.
