Francisco wrote the number 3 × 10² in standard form. His answer was 900. What
mistake did he make in order of
operations?

Francisco turned 3 into 3^2. I know this because 10^2 = 100 and Francisco multiplied 10^2 by 3.

10^2 = 100

100 * 3 = 300

In order for 300 to get to 900, the 3 would have had to have been squared.

3^2 = 9

3^2 * 10^2 = 900

In other words, he got the exponent for 3 wrong.

Step-by-step explanation:

Francisco mistakenly multiplied 10² by 3². So, he got 100*9=900

Correct answer is: 3 * 10²  = 3 * 100 = 300
