How do you write 9000000 in exponents?

To write 9,000,000 in exponential form, we first need to determine the base and the exponent. Since 9,000,000 can be expressed as 9 x 1,000,000, the base is 10 (since 1,000,000 = 10^6) and the exponent is 7 (as there are 7 zeros in 1,000,000). Therefore, 9,000,000 can be written as 10^7 in exponential form.
