Question

In exponential form, 1,100,000,000,000 can be written as:

• A. $11\times {10}^{12}$
• B. $1.1\times {10}^{11}$
• C. $11\times {10}^{10}$
• D. $1.1\times {10}^{12}$

Answer 1

The correct option is D $1.1\times {10}^{12}$

There are 11 zeros in 1,100,000,000,000, so it can be written as:$11\times {10}^{11}$

11 can further be written as 1.1 × 10.

$\left(11\right)\times {10}^{11}=(1.1\times 10)\times {10}^{11}=1.1\times (10\times {10}^{11})=1.1\times {10}^{12}$

So,option d is correct.
