how do u i make an exponent on here ?

OpenStudy (lgbasallote):

base^{exponent} ^put that in the equation editor

OpenStudy (anonymous):

click equation below. The you can write x^{-1} to get \[x^{-1}\]

OpenStudy (anonymous):

prss shift 6 example 9^7

OpenStudy (anonymous):

oh ok thanks can you guys answer this ? 4+3(4-9^0 +5^-3

OpenStudy (anonymous):

3(4 ??

OpenStudy (lgbasallote):

do you mean \[\huge 4 + 3(4- 9^0) + 5^{-3}\]

OpenStudy (anonymous):

yep thats it igbasallote

OpenStudy (lgbasallote):

9^0 is just 1...so this becomes \[\huge4 + 3(4-1) + 5^{-3}\] now simplify it... \[\huge \implies 4 + 3(3) + 5^{-3}\] do you know how to solve that now?

OpenStudy (anonymous):

nope

OpenStudy (lgbasallote):

hint: 3(3) is just 3 * 3

OpenStudy (anonymous):

-_- ofcourse

OpenStudy (lgbasallote):

so why cant you solve it then?

OpenStudy (anonymous):

\[5^{-3}=\frac{1}{5^3}\]

OpenStudy (lgbasallote):

if you know what these things mean then you should know how to solve it

OpenStudy (anonymous):

ok here is another lgbasallote solve this 7-8(2)^-3+13
