Find the product and express your answer in scientific notation.

(3.4 x 10^-5) (5 x 10^9)

17 x 10^5

Step-by-step explanation:

First you combine like terms

(3.4x5) (10^-5x10^9)

17x (10^-5x10^9)

When multiplying two exponents with the same base, you add the exponents.

17x10^4

And then you have to simplify so the coefficient it 0
1.7x10^5
