Question

(2.2*10^-3)(4*10^-2)

Answer 1

(2.2*10^-3)(4*10^-2) = 8.8*10^-5

To get this answer, we first multiply the non-exponential part of the numbers (2.2 and 4) to get 8.8. Then, we add the exponents of the numbers (10^-3 and 10^-2) to get 10^-5. Finally, we combine these two parts and write the answer in scientific notation as 8.8*10^-5.
