Kyle says 20x10^4 is the same as 20000. He reasoned that since he saw 4 as the exponent he should write 4 zeros in his answer. Is Kyle correct?

Consider the expression
20 * 10^4.

Kyle solved this expression and got the answer as 20,000. He reasoned that since he saw 4 as the exponent, so he wrote 4 zeros in his answer. Kyle is incorrect.

Consider the expression
10^4, since there is 4 in the exponent. So, we can write 4 zeros in the answer.

So,
10^4 = 10,000

Now,
20 * 10^4 = 20 * 10,000

=
200,000

Therefore,
200,000 is the correct answer.

Therefore, Kyle is not correct.
