Question

What is to be added to $2^{36}$ to get $2^{37}$?

• A. 2
• B. $$2^{36}$$
• C. $$2^{6}$$
• D. $$2^{37}$$

Answer 1

Answer:

$$2^{36}$$

$2^{36}+x=2^{37}$

$x=2^{37}-2^{36}$

$x=2^{36}[2-1]$

$x=2^{36}\times1=2^{36}$

To check it is correct,

$2^{36}+2^{36}$

$=2^{36}[1+1]$

$=2^{36}\times2$

$=2^{36+1}$

$=2^{37}$
