Use the calculator to find the product. (1. 466 × 10–8)(5. 02 × 105) What is the coefficient of the product? What is the exponen
mestny [16]

The product of the factors in the given expression comes to be 7.35932 *10^{-3}.

The given expression is:

(1.466*10^{-8} )(5.02*10^5)

We can rewrite the given expression as

(1.466*5.02)(10^{-8} *10^5)

<h3>What is the exponent addition rule? </h3>

If we have two numbers with the same base we can write the product of the numbers as a single base followed by the addition of exponents.

a^m*a^n = a^{m+n}

1.466*5.02=7.35932

10^{-8} *10^5 = 10^{-3}....from exponent addition rule

So, (1.466*10^{-8} )(5.02*10^5)=7.35932 *10^{-3}

Therefore, the product of the factors in the given expression comes to be 7.35932 *10^{-3}.
