Question

Find the product and express your answer in scientific notation.
(3.4 x 10^-5)(5 x 10^9)

Answer 1

17 x 10^5

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<a<10

1.7x10^5
