Assuming you're asking for x^2 =9, what is x;
x= 3,-3, since 3*3 = 9 and -3*-3 = 9.
It has no real roots.
200
5 to the second power
It equals 200 because 20x20 equals 200
It then equals 1/81
It has no real roots.

x2-x+8=0 Discriminant D=(-1)2-4*1*8=-31 There's no solution in real numbers There are two solutions in complex numbers: x=(1 + i*sqrt(31))/2 or x=(1 - i*sqrt(31))/2
5 to the second power
It then equals 1/81
It equals 200 because 20x20 equals 200
The answer is 1, whatever the value of a.
Two to the fifth power multiplied by three to the second power equals 288.
