BCG Matrix Question

Fourth root is the same as applying two square roots. So, using the square root key: The square root of 350/200 = 1.32288 The square root of 1.32288 = 1.15 1.15 - 1 = 0.15 or 15% Or, use the x^y key (the key saying X with y as a superscript. The fourth root is the raising to the poser of 1/4 = 0.25. Therefore (350/200= 1.75): Enter 1.75, press the x^y key, enter 0.25, press = and you get 1.15. Simlarly, the 5th root = 1/5 = 0.2. So to get the 5th root of 32, say: Enter 32, press the x^y key, enter 0.20, press = and you get 2. [Check, 2 raised to the power of 5 is 32]
