7 10

8 10

10 7

10 8

Answer 1

10^7

Explanation:

There are 7 zeros, so the number is the product of 10 multiplied by itself 7 times: 10^7.

__

Multiplying a number by 10 adds a zero on its right (moves the decimal point right one place).

1×10 = 10¹ = 10

1×10×10×10 = 10³ = 1000

1000×1000×10 = 10³×10³×10¹ = 10^(3+3+1) = 10^7 = 10,000,000
