Question

Compare the following numbers:

(i) $2.7\times {10}^{12};1.5\times {10}^8$

Answer 1

Comparing the given numbers using exponents

An exponent is the number of times a particular number is being multiplied.

Understand that here $2.7\times {10}^{12}$has $10$ multiplied $12$ times.

Similarly, $1.5\times {10}^8$ has $10$ multiplied $8$ times.

Therefore, it is clear that $2.7\times {10}^{12}$ is greater than $1.5\times {10}^8$.

Hence, the required answer is $2.7\times {10}^{12}>1.5\times {10}^8$ .
