Answer
2.5 $\times$ $10^{-2}$
Work Step by Step
We need to write 0.025 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 2.5.
The decimal point has moved 2 places to the left, so the exponent of 10 will be -2.
So, 0.025 = 2.5 $\times$ $10^{-2}$
