Question

84X10^-5/ 2X10^-10
A) 5.4x10^4
B) 4.2x 10^6
C) 0.55 x 10^7
D) 4200

Answer 1

To divide two numbers in scientific notation, divide the coefficients and subtract the exponents. The simplified answer is 4.2 x 10^6.

Step-by-step explanation:

To divide two numbers in scientific notation, divide the coefficients and subtract the exponents. In this case, we have:

84 x 10-5 / 2 x 10-10 = (84 / 2) x (10-5 / 10-10)

= 42 x 105

Therefore, the simplified answer is 42 x 105 which is equivalent to 4.2 x 106.
