3^-1 + 2^-1=

OpenStudy (luigi0210):

Anything to a negative needs to be switched

HanAkoSolo (jamierox4ev3r):

kindof like an inverse

HanAkoSolo (jamierox4ev3r):

2=1/2, 3=1/3

hero (hero):

Hint: \[2^{-1} = \frac{1}{2}\] \[3^{-1} = \frac{1}{3}\]

HanAkoSolo (jamierox4ev3r):

if you add the two together, what do you get? @elenastrawn25

OpenStudy (anonymous):

5/6

OpenStudy (anonymous):

yes that is correct and that is your answer. Do you understand?

OpenStudy (anonymous):

yes with the negative exponents they just turn into fractions

OpenStudy (luigi0210):

Yea..

HanAkoSolo (jamierox4ev3r):

yes unless you are trying to solve 5/6^-1 and its already a fraction

HanAkoSolo (jamierox4ev3r):

or i mean yikes bad example

hero (hero):

The negative in the exponent means "inverse"

HanAkoSolo (jamierox4ev3r):

if you try to solve 4/1^-1 you will get 4

HanAkoSolo (jamierox4ev3r):

lol when you think about inverse, think about flipping a fraction upside-down. or, make a whole number into a fraction (4=4/1) and flip it over

hero (hero):

\(2^{-1}\) means the inverse or reciprocal of \(2^1\)
