Come to think of it, a sum of exponentials can't decay in both directions at once, so you'll need to clarify how the signal is intended to behave for both large negative and large positive t. WebSum = x 5 + x 4 + x 3 + x 2 + x + 1. Recall that a power such as x 3 means to multiply 3 x's together (3 is called the exponent): x 3 = x · x · x. If you knew the value of x, it would be possible to compute all of the powers and add them together to find the sum. For example, if x had the value 2, Sum would be: Sum. =. lay\\u0027s layers three cheese
