Question

Choose the correct answer from the given four options:
The value of $\frac{{10}^{22}+{10}^{20}}{{10}^{20}}$ is

• A. $10$
• B. $101$
• C. ${10}^{22}$
• D. ${10}^{42}$

Answer 1

Answer: (B)

$101$

$\frac{{10}^{22}+{10}^{20}}{{10}^{20}}$

$=\frac{{10}^{20}\times {10}^2+{10}^{20}}{{10}^{20}}$

$=\frac{{10}^{20}({10}^2+1)}{{10}^{20}}$

$={10}^2+1$

$=100+1$

$101$
