Simplify (frac{(1.25 times 10^{-4}) times (2.0 times 10^{-1})}{(6.25 times 10^5)})

Simplify (frac{(1.25 times 10^{-4}) times (2.0 times 10^{-1})}{(6.25 times 10^5)})
  • A.
    4.0 x 10-3
  • B.
    5.0 x 10-2
  • C.
    2.0 x 10-1
  • D.
    5.0 x 10-3
Correct Answer: Option A
Explanation

(frac{(1.25 times 10^{-4}) times (2.0 times 10^{-1})}{(6.25 times 10^5)}) = (frac{1.25 times 2}{6.25}) x 104 – 1 – 5
(frac{2.50}{6.25}) x 10-2 = (frac{250}{625}) x 10-2
0.4 x 10-2 = 4.0 x 10-3
