Please help me. I am so stressed out. Therefore, I was wondering if you can check my answers and help me understand what I did wrong. Thanks

okay, so number 4 on the first 1
OpenStudy (anonymous):
your first step was right: 9x^-2/18x^15

but it reduces to 1/2x^17
OpenStudy (anonymous):
a negative exponent in the numerator is a positive exponent in the denominator
OpenStudy (anonymous):
so when you combine them you are actually adding 2 to 15
OpenStudy (anonymous):
the 9/18 reduces to 1/2; the x's do not cancel
OpenStudy (anonymous):
do you follow what i'm saying?

yup got it thank you!!
OpenStudy (anonymous):
okay now the next one
OpenStudy (anonymous):
you need to deal with the -2 exponent before you can mess with the stuff on the inside
OpenStudy (anonymous):
again the -2 exponent moves everything to the denominator and squares it
OpenStudy (anonymous):
so you'll have (1/8p^6...etc)^2
