a) Assume you have the Scientific calculator where some keys are broken. Only keys which work are digits 0 to 9, +,-,x, Divide, ln and e^x. Describe how you can use this calculator to compute square root of any whole number.
b) Assume instead you have another calculator, where it is same as other one but e^x key is broken and 10^x works instead. How can you use this calculator to compute square root of any whole number . (0 to 9, +,-,x, Divide, ln and 10 ^x works)
