How do i solve rank of a determinant?
Matrix inverses and determinants, square and nonsingular, the equations AX = I and XA = I have the same solution, X. This solution is called the inverse of A.
Why a number to the zero power is always equal to 1?
It is a consequence of the definition of the index laws. xa * xb = xa+b If you put b = 0 in the above equation, then you get xa * x0 = xa+0 But a+0 = a so that the right hand side becomes xa Thus the equation now reads xa * x0 = xa For that to be true for all x, x0 must be the identity element for multiplication. That is x0 = 1 for all x.
The sum of Xa and Xb for any solution is always 1?
Circle
Why is 6 raised to the 0 power 1?
Any number raised to the power 0 is 1. This follow from the law of multiplications of power: xa * xb = xa+b Now, if you put b = 0, you get xa + x0 = xa+0 and since a+0 = a, the right hand side is xa. So you have xa * x0 = xa and using the property of the multiplicative identity, xa = 1.
Which is bigger 4 to the power of 3 squared or 2 to the power of three to the power of 4?
Neither. They are equal.(43)2 is the same as 46 = 4096 ...remember (xa)b = xa*b(23)4 is the same as 212 = 4096
