Question 927573: a.)
Suppose you have a Scientific calculator where some keys are broken. The only keys that work are digits 0 to 9, +,-,x, Divide, ln and e^x.
Explain how you can use this calculator to calculate the square root of any whole number.
b.)
Suppose instead you have another calculator, where it is the same as the other one but the e^x key is broken and the 10^x works instead. How can you use this calculator to calculate the square root of any whole number . (0 to 9, +,-,x, Divide, ln and 10 ^x works)

KEY SEQUENCE
Enter number to be processed.
press natural log key.
Press DIVIDE button.
Press TWO button.
---from here, some calculators may work differently;
press the equality button;
use the result to obtain e^(display), according to what is displayed for previous step. You are trying to find antilog base e of the display.
