The solution to the equation \sqrt{(X - 4)(X + 4)} = 3 is X = 5 and X = -5.
The solution involves finding the values of a and b, given a*a = 8 and a*b = 24. Then, b*b is calculated, resulting in a final answer of 72.
Cramer's rule is used to solve a system of four linear equations with four unknowns, resulting in the values of x1, x2, x3, and x4.
The square root of 19 squared plus 19 plus 20 is calculated to be 20.
To find (a+b)^2, given a^2 + b^2 = 29 and ab = 10, substitute the given values into the equation (a+b)^2 = a^2 + 2ab + b^2, resulting in (a+b)^2 = 49.
The only real solution to the cubic equation a^3 + a^2 - 36 = 0 is a = 3.
The solution to the equation X^3 - X^0 = 26 is X = 3.
The equation (x-1)^(|x|-4) = 1 has solutions x = -4, 0, 2, and 4.
The equation x^2 - 2x = 0 has two solutions, x = 0 and x = 2, not just x = 2.
The solution for b in the equation 2^(b^2+2) = 64 is b = 2.
The multiplication of the two given matrices results in a 2x3 matrix with entries calculated by multiplying corresponding rows and columns of the matrices and summing the products.
