What should A and B equal?

marking brainliest for correct answer!!

Step-by-step explanation:

Let set up the equation

First, let solve for a.

Since our product base is 10 and one of our factor base is 2. We need to find a number to multiply 2 by to get 10.

Let replace a in the equation,

Using the rule that if two exponet have the same power but different bases, we multiply the bases and keep the same power.

We already multiplied the bases.

The power stay the same so b=-3

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
