Brackets and parentheses in Wolfram|Alpha

By combining these,

[1] (4*pi(0.5)(6.0221409*10^23)) - Wolfram|Alpha

[2] (2*1.67*10^(-27)/(2*pi(1.38*10^(-23)((300)))))^(3/2) - Wolfram|Alpha

I want this answer:

But my parantheses are wrong and I need some help to get them straight:

My first guess (and it is a quick guess) is that the issue is how pi is getting interpreted. The two interpretations I see are:

  • the constant pi
  • the function pi(x) which returns the number of primes less than or equal to x

If you want the constant, I suggest always explicitly including the * between pi and ( so that you are guaranteed to get multiplication of the constant.
