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

1 answer

We can set up the equation:

8×10^3 = 40(a×10^2)

To solve for a, we can simplify both sides of the equation and then isolate a:

8×10^3 = 40a×10^2

8×10^3 = 40a×10^2

8×10^3 = 40a×10^2

8×10^3 = 400a

Divide both sides of the equation by 400:

(8×10^3)/400 = a

20 = a

Therefore, the value of a is 20.
