buongiorno a tutti

come si fa a scrivere un codice del genere?

(((-0,0000336713*((°C*9/5)+32)^4+0,0105207916*((°C*9/5)+32)^3-1,2495985607*((°C*9/5)+32)^2+67,0024722564*((°C*9/5)+32)-1374,6540546564) LN(1%)+ (-0,000003773((°C*9/5)+32)^4 + 0,0011788625*((°C

*9/5)+32)^3 - 0,1400139318*((°C

*9/5)+32)^2 + 7,5072379375*((°C

*9/5)+32) - 154,0188143761))-((-0,0000336713*((°C

*9/5)+32)^4+0,0105207916*((°C

*9/5)+32)^3-1,2495985607*((°C

*9/5)+32)^2+67,0024722564*((°C

*LN(40%)+ (-0,000003773*((°C*9/5)+32)^3 - 0,1400139318*((°C

*9/5)+32)^2 + 7,5072379375*((°C*9/5)+32) - 154,0188143761)))/(LN(4000%)/LN(2)))))

how do you write such a code?
