Question

Which has a larger value: 4 x 10^2 or 7 x 10^4?

Answer 1

Answer:

7 x 10^4

Step-by-step explanation:

4 x 10^2 equals to 400, when 7 x 10^4 equals to 70,000

Answer 2

Answer:

$7$× $10^{4}$

Step-by-step explanation:

Because the exponent means that the number is being multiplied by itself that many times. Like $10^{4}$ means 10000 and that times 7 is 70000.

$10^{2}$ would be 100 and 100 times 4 is 400. Now to determine is 400 or 70000 larger? 70000 is larger.

Hope that helps and have a great day!
