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. As learning progresses they are challenged to consider indices with negative and fractional powers. Using those two values and operand, it will perform Arithmetic Operations. Calculate any Power of i (the Square Root of -1) When learning about imaginary numbers, you frequently need to figure out how to raise i to any power. When an exponent is 1, the base remains the same. 2^-2 = 1/2^2; If a number is raised to a power expressed as a fraction, then it should be rooted, e.g. Negative exponent ; A negative exponent represents which fraction of the base, the solution is. e^x function is above ln function in the scientific calculator. Conversions. Our summation calculator can easily calculate the sum of any numbers you input. You can also calculate numbers to the power of large exponents less than 1000, negative exponents, and real numbers or decimals for exponents. For many applications, defining 0 0 as 1 is convenient.. a 0 = 1 . Negative Predictive Value Calculator.
