it should actually read y^-5y
OpenStudy (anonymous):
any number raised to a negative power is equivalent to 1 divided by that number raised to a positive power
OpenStudy (anonymous):
x^-y = 1/x^y
OpenStudy (anonymous):
thank you
OpenStudy (anonymous):
sure, would you like to write the answer so i can check it?

sure give me a minute pls
OpenStudy (anonymous):
y^-5y = y5y= y^6 ?
OpenStudy (anonymous):
not quite
OpenStudy (anonymous):
ohhh pls help me understand more
OpenStudy (anonymous):
ok

see how i said that x^-y = 1/x^y ?
OpenStudy (anonymous):
alll you need to do is put the number in the denominator and get rid of the negative sign in front of the exponent
OpenStudy (anonymous):
y^y/5 ?
OpenStudy (anonymous):
a litter closer
OpenStudy (anonymous):
5/y^y?

do I add the 'y's?
OpenStudy (anonymous):
nope
OpenStudy (anonymous):
you ignore the exponents for now and concentrate on only the negative sign
OpenStudy (anonymous):
for example, 4^-1 = 1/4^1 = 1/4
OpenStudy (anonymous):
so is it 1/y^5y?

wait
OpenStudy (anonymous):
ok ok
OpenStudy (anonymous):
you have the right answer
OpenStudy (anonymous):
ohhhh tytytyty :)
OpenStudy (anonymous):
just for another example for when you see fractions with negative exponents. x^-x/y^-y = y^y/x^x

just reverse the numerator and denominator and remove the negative sign from the exponent
