find ((4.8x10^(6))(3.6x10^(3)))/((2x10^(5))) expressed in scientific notation

Question

a. 8.64 x 10^4
b. 8.64 x 10^6
c. 8.64 x 10^8
d. 17.28 x 10^4
e. 17.28 x 10^8

Answer 1

To solve this problem, we first need to multiply the numbers in the numerator and then divide by the number in the denominator.

(4.8 x 10^6) x (3.6 x 10^3) = 17.28 x 10^9

Now we divide by (2 x 10^5):

(17.28 x 10^9) / (2 x 10^5) = 8.64 x 10^(9-5) = 8.64 x 10^4

So, the answer is a. 8.64 x 10^4.
