Question 88897: Simplify each expression
1. (y^-4y^5)^2
2. Brackets around the whole problem -3x^8x^-3 divided by 6x^-3x^4 then outside the brackets is a ^3
3. x^8nx^3n
4. x^2n divided by x^5n

1. (y^-4y^5)^2 = [y^1]^2 = y^2
-------------------------
2. Brackets around the whole problem -3x^8x^-3 divided by 6x^-3x^4 then outside the brackets is a ^3
= [(-3x^5)/(6x)]^3
= [-x^4/2]^3
= [-x^12]]/8 = (-1/8)x^12
----------------
3. x^8nx^3n
= x^11n
------------------
4. x^2n divided by x^5n
= 1/x^3n
