Answer:
The number is either 2 or 1
Step-by-step explanation:
Where x is the unknown number, the square of may be interpreted as x², then the square of the number minus three times the number will be equivalent to
x² - 3x
If this is equal to 2 then
x² - 3x = -2
such that
x² - 3x + 2 = 0
This may be solved using factorization of quadratic equation
x² - 2x -x + 2 = 0
x(x - 2) -1(x- 2) = 0
(x -2)(x-1) = 0
x = 2 or 1
1/64, because if its a negative exponent you use the reciprocal and then 4 to the fourth power is 64
