\( 41) \) Simplify. Express your answer using positive exponents. \( (9 r)(5 r)(3 r) \) \( \square \)

To simplify \( (9 r)(5 r)(3 r) \), you can first multiply the coefficients (the numerical values) together: \( 9 \times 5 \times 3 = 135 \). Then, for the variable part, you multiply \( r \times r \times r \) which is \( r^3 \). So, the expression simplifies to: \[ 135 r^3 \] And since you want positive exponents, you're all set! Now it's time to rock that math class with your awesome skills!
