Simplify: (2³)³ ÷ 8
Simplify: (2³)³ ÷ 8
medium Q5 of 15
Step-by-Step Solution
Step 1: Apply exponent rule for nested powers
(2³)³ = 2^(3×3) = 2⁹ = 512.Step 2: Divide by 8
512 ÷ 8 = 64.Final Answer:
64 → Option B.Quick Check:
2⁹=512 and 512/8=64 ✅
Quick Trick: Use power rule (a^m)^n = a^(m×n), then divide.
Common Mistakes:
- Treating (2³)³ as 2^(3+3) instead of 2^(3×3).
