Factor x13 from x23 x23SolutionFactor x13 x23 x23 we can

Solution

Factor x^(-1/3)

( x^2/3 + x^-2/3 )

we can write x^2/3 = x^(-1/3)x^(1/3)x^(2/3)

x^(-2/3) = x^(-1/3)x^(-1/3)

x^(-1/3)x^(1/3)x^(2/3) + x^(-1/3)x^(-1/3)

Taking out x^(-1/3) as common factor:

x^(-1/3) { x^(1/3+2/3) + x^(-1/3) }

x^(-1/3) { x + x^(-1/3) } Solution
