guest     3^3 = 3*3*3 = 27

so the answer is 9x

sqrt(50)

sqrt(50) = 7.0710678118654752

I just did it on the forum calc exactly as you said and I got the proper approximation ://

29490(1+14/1200) to the power of 48

29490(1+14/1200)^48 = 51460.2540305744241816

Simplify

\(\frac{36k^2m^4}{30k^5m}\\ =\frac{6m^3}{5k^3}\\\)

10^-0.7 = 0.199526231496888

I just put it in as 10  [x^y]  -0.7

15r + 10=5(3r+2)

Very impressive Heureka   

We need to know how big a bottle is Or what percentage is active ingredient.

square root

\(\sqrt{500}=\sqrt{100*5}=10\sqrt{5}\)

arc tan is the same as inverse tan

so use

[2nd] [atan]
