144/36 in lowest terms is 4.
To show my work, here.
1. Find the GCF of 144 and 36 so now we divide (144/36 = 4 and 36/36 is 1)
2. Now we have 4/1 so we simplify again so divide 4/1 and its 4
I hope this helps you out
Answer:
y^2/x^6
apply exponent rule:
x^-2/x^4=1/x^4-(-2)=y/y^-1 x^4 -(-2)
then you subtract 4-(-2)=6
y/x^6 y^-1
cancel out the common factor: y^-1 and you get
y^2
------
x^6
I solved it and i think the answer is 20 :)
