Perform the following calculations without rewriting the numbers in decimal form.

RSB [31]

Answer:

Answer will be $140\times 10^{13}$

Step-by-step explanation:

We have to perform the calculation $(1.42\times 10^{15}-2\times 10^{13})$ without changing into decimal

$1.42\times 10^{15}$ can be written as $142\times 10^{13}$

So $1.42\times 10^{15}-2\times 10^{13}=(142\times 10^{13}-2\times 10^{13})$

Now taking $10^{13}$ common

$10^{13}(142-23)=140\times 10^{13}$
