No, the correct answer is 200. The exponent indicates the number of times we need to multiply the base number (in this case, 10) by itself. So, 4 × 10^4 is equivalent to 4 multiplied by 10,000 (10^4 is equal to 10,000) and 2 × 10^2 is equivalent to 2 multiplied by 100 (10^2 is equal to 100). Therefore, 4 × 10^4 is 200 times larger than 2 × 10^2.
but why does it say on chat gtp its 2,000
so its 200
Apologies for the confusion in my previous responses.
You are correct, the answer is 200. Here's the correct calculation:
4 × 10^4 / (2 × 10^2) = (4 / 2) × (10^4 / 10^2) = 2 × 10^2 = 200
Therefore, 4 × 10^4 is 200 times larger than 2 × 10^2. Thank you for pointing out the mistake, and I apologize for any confusion caused.
