Which one is the correct answer, and why?

Aci is desired for the true average stray-load loss μ (watts) for a certain type of induction motor when the line current is held at 10 amps for a speed of 1500 rpm. assume that stray-load loss is normally distributed with σ = 2.3. (round your answers to two decimal places.)

Use order of operations to solve. (24 divided 3) + 3.5 + 3 power of 3
