$\tt{ {2}^{ - 3} + {2}^{ - 2} }$

$\\ \tt{⇢ \frac{1}{ {2}^{ 3} } + \frac{1}{ {2}^{2} } }$

$\\ \tt{ ⇢\frac{1}{8} + \frac{1}{ 4} }$

$\\ \tt{ ⇢\frac{1 + 2}{8} }$

$\\ \tt{⇢ \red {\frac{3}{8} }}$

$\: \: \: \: \: \: ⛬ \: \rm{The \: answer \: is \: \red{ \frac{3}{8} }}.$

Answer 2

Step-by-step explanation:

Now, 1/(2)^3 + 1/(2)^2

1/8 + 1/4

Now, take lcm,

1+2/8

3/8

Hence, your answer is 3/8.
