F9 CBE equations not working in excel, Miller-Orr

Hi,

I hope someone can help me.

I have tried doing the Miller-Orr equation in excel many different ways but I cannot get the right answer, when I do it on my calculator it is correct but it’s hard to show workings in excel that you have done on the calculator.

I am typing into excel =POWER(3*((3/4*18*1000000)/0.00014),1/3) and it is coming up with 6613.67

I am typing it into my calculator 3*((3/4*18*1000000)/0.00014) to the power of function button 1/3 and it is coming up with the correct answer 13756.98

What am I not understanding here?

Thanks 🙂
