#### Answer

9.7 $\times$ $10^{-2}$

#### Work Step by Step

We need to write 0.097 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 9.7 The decimal point has moved 2 places to the left, so the exponent of 10 will be -2. So, 0.097 = 9.7 $\times$ $10^{-2}$
