Answer:
So it by its formula you can solve it bye
What is your question? This doesn't state a specific question.
X^4=256
x^4-256=0
(x^2)^2-(16)^2=0
(x^2+16)(x^2-16)=0
either x^2+16=0
it gives complex roots.
or x^2-16=0
or x^2-4^2=0
(x+4)(x-4)=0
either x+4=0,x=-4
or x-4=0
x=4
12:8 can also be written as

To find the percent you have to do 12÷8 and that equals 1.5, then you have to do 1.5×100 and that equals 150. The ratio, 12:8 as a percent is 150%
