Is (x2 + y2)2 the same as x4+ y4? If not, explain why and simplify it correctly.

not sure but i think yes (x2+y2)² is equal to x4+y4 because x2^2 and y2^2 should equal 2*2=4

Step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
