In mathematics a square root of a number x is a number y such that y. Lets get some practice solving some exponential equations and we have one right over here we have 26 to the 9x plus 5 power equals 1 so pause the video and see if you can tell me what X is going to be well the key here is to realize the 26 to the 0th power to the zeroth power is equal to 1 anything to the zeroth power is going to be equal to 1 0 to 0 power we can discuss it some other. Two online calculators and solvers for exponential equations of the form b x a are presented.

If we can write a single term with the same base on each side of the equation we can equate the exponents. Use exponents laws to simplify. In other words you have to have some base to some power equals the same base to some other power where you set the two powers equal to each other and solve the resulting equation.
