4.2*10to the 6th or 4,200,000

Step-by-step explanation:

First you have to know that you are multiplying these two numbers. When you multiply exponents like there you add the matissa's (6&7) and add the exponents.

6*10to the 2 * 7*10to the 3rd

42 * 10to the 2+3

42*10to the 5th

Something else you need to know is your matissa cant be higher than 10

So:

4.2 * 10to the 6th is your answer
