Simplify Expression with Fractional Exponents











































Simplify exponent Expression

   • Simplify the following expression

           (9x)2/3 + (2y)2/3 + z2/3

           Use PEMDAS order of operations

           Note that the denominator of the fractional exponent is the index of the radical, and the numerator is the exponent of the radicand (the expression which is inside the radical).

Answer:


           (9x)2/3 + (2y)2/3 + z2/3

           (9x)(2*⅓) + (2y)(2*⅓) + z(2*⅓)

           (9²x²)(⅓) + (2²y²)(⅓) + (z²)(⅓)

           (9²x²)(⅓) + (2²y²)(⅓) + (z²)(⅓)

           ∛(9²x²) + ∛(2²y²) + ∛(z²)

           ∛(81x²) + ∛(4y²) + ∛(z²)

           3∛(3x²) + ∛(4y²) + ∛(z²)



Final Answer:


                 3∛(3x²) + ∛(4y²) + ∛(z²)
