is the the sum rational or irrational ?π +24

Simplify the expression. \[ x^{-\frac{1}{4}} \] \( x^{\frac{1}{2}} x^{\frac{1}{3}} \) Write your answer using only positive exponents. Assume that all variables are positive real numbers.

Rewrite the equation in \( A x+B y=C \) form. Use integers for \( A, B \), and \( C \). \[ y=-\frac{1}{3} x+6 \]

What is the quotient of \(\frac { 1+ i} { 3+ 4i} \)?

11) Sarah is planning a birthday party for her friends and family and wants to make sure that the number of total guests is neither too few nor too many. She has space to comfortably host between 15 and 30 total guests. Sarah has 4 family members that are already planning on coming and is trying to decide how many friends she can invite.
