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.
2 to the second power, or (2^2), equals 4. Similarly, 1 to the second power, or (1^2), equals 1. Therefore, (2^2 = 4) and (1^2 = 1).
200
5 to the second power
It equals 200 because 20x20 equals 200
It has no real roots.
2 to the second power, or (2^2), equals 4. Similarly, 1 to the second power, or (1^2), equals 1. Therefore, (2^2 = 4) and (1^2 = 1).
14
4
200
5 to the second power
It equals 200 because 20x20 equals 200
It then equals 1/81
The answer is 1, whatever the value of a.
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
Two to the fifth power multiplied by three to the second power equals 288.
