9.75 × 10^11 <----
6.4 × 10^41
9.75 × 10^41
Is this correct I need to get least a b

correct

To find the product of two numbers expressed in scientific notation, you can simply multiply their coefficients and add their exponents.

In this case, we have:
2.5 × 10^(-15) and 3.9 × 10^26

First, multiply the coefficients: 2.5 × 3.9 = 9.75

Then, add the exponents: -15 + 26 = 11

Therefore, the product is 9.75 × 10^11.

Therefore, the correct answer is: 9.75 × 10^11.
