Can someone tell me the answers? Like for example point A is 5,3) please help

Sure! Please give if I'm correct, and thank you!

A= 5,3

B= 0,0

C= -9,-4

D= -10,4

E= 4,-8

F= 10,10

G= -4,0

H= 0,7

I= -6,-8

J= 9,-2

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)

step-by-step explanation:

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?
