Answer
1.3 $\times$ $10^{7}$
Work Step by Step
We need to write 13,000,000 as the product of a number greater than or equal to 1 and less than 10, and an integral power of 10.
The number greater than or equal to 1 and less than 10 will be 1.3.
The decimal point has moved 7 places to the right, so the exponent of 10 will be 7.
So, 13,000,000 = 1.3 $\times$ $10^{7}$
