Answer 1

It is C.
I hope i helped!

Answer 2

Option C is correct.

Explanation:

Given two numbers

`10* 10^9\text{ and } 99* 10^6`

we have to estimate about many times a number larger than another.

To estimate we have to divide.

`(10* 10^9)/(99* 10^6)` → (1)

As
`(x^a)/(x^b)=x^(a-b)`

Equation (1) implies

`(10* 10^(9-6))/(99)`

⇒
`(10* 10^3)/(99)`

⇒
`(10000)/(99)=101.01\sim 100\thinspace times`

Hence, 100 times larger.

Option C is correct.
