To find the answer, you multiply 80 by itself 4 times as follows:
80 x 80 x 80 x 80 =
And you get the answers which is
Answer:
x = 13
y = 9
Step-by-step explanation:

A number is divisible by two if you get no remainder when you divide that number by two. Even numbers are divisible by two. Odd numbers are not divisible by two.
y(x)=sin^2 (x/4)+12sin(x/4)
y(x) = sin^2(x/7) +16sin(x/7)
From the Chain Rule,
y'(x) = 2sin(x/4)*(1/4)cos(x/4) + 12(1/4)cos(x/4).
At x=4pi, the slope of the tangent line is
y'(4pi) = 2sin(4pi/4)*(1/4)cos(4pi/4) + 12(1/4)cos(4pi/4).
= 2sin(pi)*(1/4)cos(pi) + 12(1/4)cos(pi)
= 2(0)(1/4)(-1) + 12(1/4)(-1)
= -3
The angle (in radians) that the tangent line makes to the
positive x-axis is
pi - arctan(3)= 1.249 rad =71.565 degree
