Apply index laws: Evaluate (10)^(200) ÷ (10)^(196) and report the exact numerical value.

Difficulty: Easy

Correct Answer: 10000

Explanation:


Introduction / Context:
This is a direct application of exponent subtraction for division with the same base. The goal is to demonstrate fluency with a^m / a^n = a^(m−n).


Given Data / Assumptions:

  • (10)^(200) ÷ (10)^(196)
  • Base is identical (10).


Concept / Approach:
Use the law a^m / a^n = a^(m−n). Subtract exponents and then evaluate the resulting power of 10.


Step-by-Step Solution:
(10)^(200) ÷ (10)^(196) = 10^(200 − 196) = 10^410^4 = 10000


Verification / Alternative check:
Think place value: shifting decimal four places to the right matches multiplying by 10000.


Why Other Options Are Wrong:
1000 (10^3), 100 (10^2), or 100000 (10^5) correspond to incorrect exponent differences. 10 is 10^1.


Common Pitfalls:
Accidentally adding exponents during division. Remember division subtracts exponents.


Final Answer:
10000
