Rules of Exponents
Rules of Exponents Zero-Exponent Rule: $displaystyle {{a}^{0}}=1$ this means that each number raised to the zero power is 1. Worked example 1: 50 = 1 (-3)0 = 1 $displaystyle {{(5{{x}^{6}}{{y}^{2}})}^{0}}=1$ $displaystyle {{left( frac{2}{x} right)}^{0}}=1$ Power of a Power: $displaystyle {{left( {{a}^{m}} right)}^{n}}={{a}^{mn}}$ So, when you raise a power to a power you have to multiply the exponents. Worked example 2: […]
