I need help with this plsss - image included

1 i hope this helps

Step-by-step explanation:

a) 3570

b) 32 or -8y+32

c) 2y^3-2y^2+8y

d) 5x-5y-4(x-y)

e) 4x(x-y)+y(x-y)

Page 2:

a) 125 93/t

b) -x(4x+3)

c) (a+b)(x-y)

d) (4x+3)(3x^2-5)

e) -x (a-b-3)

Page 3:

a) P=A-1

b) D=S+X

c) My poor back hurts at this point so I quit here -

d) If you really need these two I'm happy to come back and answer them though! let me know in the comments ^^

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
