Question

Evaluate the quotient of 1.05 x 103 and 1 x 103:

A.) 1.05 x 109
B.) 1.05 x 106
C.) 1.05 x 100
D.) 1.05 x 10-6

Answer 1

The answer would be Letter C

(1.05 x 10^3)
-----------------
(1 x 10^3)

Divide the 1.05 by 1 and get 1.05
Divide 10^3/10^3 and get 10^(3-3) = 10^0
So: 1.05 x 10^0

Answer 2

C)
`1.05* 10^0`

Explanation:

Here, the given expression is,

`(1.05* 10^3)/(1* 10^3)`

`=(1.05* 10^3* 10^(-3))/(1)`
`(a^m=(1)/(a^(-m)))`

`=1.05* 10^(3-3)`
`(a^m.a^n=a^(m+n))`

`=1.05* 10^0`

Which is the required quotient.

Option 'C' is correct.
