_{To solve exponential equations with same base, use the property of equality of exponential functions . If b b is a positive number other than 1 1 , then bx = by b x = b y if and only if x = y x = y . In other words, if the bases are the same, then the exponents must be equal. Solve the equation 42x−1 = 64 4 2 x − 1 = 64 . Note that the ...Algebra 2 students extend their knowledge of the real number system by working with complex solutions and factors of polynomials. Students expand their experience with polynomial functions, finding complex zeros and interpreting solutions. Students extend properties of exponents to using rational exponents when factoring, solving, and evaluating.Exponential equations can have any positive integer as the base number except for one .
