Which one is smaller 5.8x10^-3 or 4.5x10^-3

((x)(x))/(3-x) = 1.8x10^-5 how do I solve for x

1.8x10^-6

0.8x10^-3

4.8x10^5^2 divide 2.8x10^4

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

For what value of a will 8x10 to the power of 3 be 40 times larger than ax10 to the power of 2?

What is (8x10) + (4x1)+ 2 x 1/100)
