x^12/4 /x^1/4
OpenStudy (phi):
one way to remember what to do is remember this
\[ x \cdot x = x^2 \]
and x is the same as \( x^1\)
so you get this
\[ x^1 \cdot x^1= x^2 \]
notice the key idea 1+1 = 2
OpenStudy (phi):
add exponents (if you have the same base)

and hopefully you know
\[ \frac{x\cdot x}{x} = x \]
or with exponents
\[ \frac{x^2}{x^1} = x^1 \]
OpenStudy (gabylovesyou):
so add 5/4 + 7/4 = 12/4 = 3
OpenStudy (gabylovesyou):
so x^3 ?
OpenStudy (anonymous):
yes
OpenStudy (phi):
exponents that are fractions or negative still work.
so yes add

but x^3 - x^1/4
OpenStudy (phi):
it would be easier to leave it 12/4 because you then subtract off 1/4
