For what value of a will 8x10^3 be 40 times larger than ax10^2

Answer 1

To find the value of a that makes 8x10^3 equal to 40 times ax10^2, we can set up the equation:

8x10^3 = 40(ax10^2)

Simplify by dividing both sides by 40:

8x10^3 / 40 = ax10^2

200 = ax10^2

Now we can solve for a by dividing both sides by 10^2:

200 / 10^2 = a

a = 2

Therefore, the value of a that makes 8x10^3 equal to 40 times ax10^2 is a = 2.
