for what value of a will 8 × 10 3 be 40 times larger than a × 10 2 ?(1 point)

Answer 1

To find the value of a, we can set up an equation:

8 × 10^3 = 40(a × 10^2)

We can simplify this equation:

8 × 1000 = 40a × 100

8000 = 4000a

Divide both sides of the equation by 4000:

a = 2

So, the value of a that makes 8 × 10^3 40 times larger than a × 10^2 is a = 2.
