It is C.
I hope i helped!

Answer 2

Answer:

Option C is correct.

Step-by-step explanation:

Given two numbers

$10\times 10^9\text{ and } 99\times 10^6$

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

To estimate we have to divide.

$\frac{10\times 10^9}{99\times 10^6}$ →  (1)

As $\frac{x^a}{x^b}=x^{a-b}$

Equation (1) implies

$\frac{10\times 10^{9-6}}{99}$

⇒ $\frac{10\times 10^3}{99}$

⇒ $\frac{10000}{99}=101.01\sim 100\thinspace times$

Hence, 100 times larger.

Option C is correct.
