  • Basic rules for exponentiation - Math Insight
    The rules Product of exponentials with same base If we take the product of two exponentials with the same base, we simply add the exponents: xaxb = xa+b (1) (1) x a x b = x a + b To see this rule, we just expand out what the exponents mean Let's start out with a couple simple examples

  • Expansion of $a^x$- $b^x$ - Mathematics Stack Exchange
    As a side note, when b = 1 b = 1 the formula xn − 1 = (x − 1)(1 + x +x2 +x3 + ⋯ +xn+1) x n − 1 = (x − 1) (1 + x + x 2 + x 3 + ⋯ + x n + 1) is very useful in many exercises You can regard it also as the sum of a geometric series 1 + x +x2 + ⋯ +xn = 1−xn+1 1−x 1 + x + x 2 + ⋯ + x n = 1 − x n + 1 1 − x

  • Algebra Formulas - BYJUS
    If α and β are the two roots of the equation ax 2 + bx + c = 0 then, α + β = (-b a) and α × β = (c a) If the roots of a quadratic equation are α and β, the equation will be (x − α) (x − β) = 0
