Answer:

5 and 8

Explanation:

Let's call the smaller number "x". According to the problem, the larger number is 3 greater than x, which means it can be written as "x + 3".

We also know that the product of these two numbers is 40, so we can set up the following equation:

x(x+3) = 40

Expanding the left side, we get:

x^2 + 3x = 40

Rearranging terms, we get a quadratic equation:

x^2 + 3x - 40 = 0

We can solve this equation using factoring or the quadratic formula.

Factoring:

(x + 8)(x - 5) = 0

So x = -8 or x = 5. We can reject the negative value since we're looking for two positive numbers, so the smaller number is 5 and the larger number is 5 + 3 = 8.

Therefore, the two numbers are 5 and 8.
