To solve your equation using the Equation calculator, type in your equation … 2. To solve exponential equations with the same base, which is the big number in an exponential expression, start by rewriting the equation without the bases so you're left with just the exponents. Try this example now! Will calculate the value of the exponent. It represents a growth that is compounded every period by a certain rate (or percentage) The exponential function y =bx y = b x is one-to-one, so its inverse, x =by x = b y is also a function. The other will work on more complicated exponential equations but can be a little messy at times. Use a calculator to check the answer we found to the equation in example 3. x(t) = x 0 × (1 + r) t. x(t) is the value at time t. x 0 is the initial value at time t=0. The first step is to enter the initial value (x0). The calculator will find the solution of the given ODE: first-order, second-order, nth-order, separable, linear, exact, Bernoulli, homogeneous, or inhomogeneous. When an exponent is 0, the result of the exponentiation of any base will always be 1, although some debate surrounds 0 0 being 1 or undefined. a 1 = a . This calculator has three text fields and two active controls that perform independent functions of the calculator. Submit Show explanation View wiki. There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring (direct factoring, grouping, AC method), completing the square, graphing and others.
