Answer:
Step-by-step explanation:
a = x^4
a^2 - 13a +36 = 0
(a-4)*(a-9)=0
a = 4, a = 9
so
x^4 = 4, x^4 = 9
x = + or - 4th root of 9 and 4
Answer: d=sqrt(41) =6.4031
Step-by-step explanation:
We know that the distance between the two points (x 1 ,y 1 ) and (x 2 ,y 2
) is
d= sqrt((x2-x1)^2 +(y2-y1)^2 )
as given
x1=2 ,x2=6 ,y1=3 ,y2=8
d=sqrt((6-2)^2+(8-3)^2 )
d= sqrt((4)^2+(5)^2
d=sqrt(16+25)
d=sqrt(41) =6.4031
