Rewrite the rational exponent as a radical by extending the properties of integer exponents. ps for the picture this added on to
it = 2² By finding the quotient of the bases to be one fourth, and cancelling common factors
By finding the quotient of the bases to be one fourth, and simplifying the expression
By simplifying 8 to 2³ to make both powers base two, and subtracting the exponents
By simplifying 8 to 2³ to make both powers base two, and adding the exponents
Simple sum. The symbol Σ (sigma) is generally used to denote a sum of multiple terms. This symbol is generally accompanied by an index that varies to encompass all terms that must be considered in the sum.
