​

Answer 1

Answer:

5

Step-by-step explanation:

(1/2)^-1 +(1/3)^-1

=2+3

=5

Answer 2

ANSWER:

$\huge{ \mathfrak{ \underline{ \underline \pink{5}}}}$

STEP - BY - STEP EXPLANATION:

${ \tt{ \dfrac{1}{ {2}^{ - 1} } + \dfrac{1}{ {3}^{ - 1} } }}$

Using

${ \rm{ {x}^{ - a} = \dfrac{1}{ {x}^{a} } }}$

${ \tt{ \implies \dfrac{1}{ \frac{1}{2} } + \dfrac{1}{ \frac{1}{3} } }}$

Using

${ \rm{ \to \dfrac{x}{ \frac{y}{z} } = \frac{xz}{y} }}$

${ \tt{ \implies \dfrac{2}{1} + \dfrac{3}{1} = 2 + 3 }}$

$\implies5$

Hence,

${ \bf{ \dfrac{1}{ {2}^{ - 1} } + \dfrac{1}{ {3}^{ - 1} } \to5}}$
