An exponent is a mathematic notation indicating that a number is multiplied by itself a certain number of times. The number to be multiplied by itself is called the base. The number of times the base will be multiplied by itself is the exponent. For example, a^n means "a multiplied by a n times," where a is the base and n is the exponent. Exponents sometimes need to be removed to find the answer to equations.
Find the multiplicative inverse of the exponent you wish to remove. This is simply 1/n, where n is the exponent. Make a note of this value. In this example, we will use the equation (x + 2)^2 = 4. The exponent is 2, so the multiplicative inverse is 1/2.
Fix the power of the left hand side of the original expression to the value found in step 1. In this example, the left side of the equation will be ((x + 2)^2)^(1/2). The exponents of 2 and 1/2 cancel out, leaving x + 2.
Fix the power of the right side of the original expression to the value found in step 1. In this example, this is 4^(1/2), which is equal to 2. This ensures the equation is balanced and the exponent is removed.
