Nested function calls 1

In math and programming we say we evaluate a function when we replace arguments with specific values. So if we type log2(16) we evaluate the log2 function to get the log base 2 of 16 which is 4.

In R it is often useful to evaluate a function inside another function. For example, sqrt(log2(16)) will calculate the log to the base 2 of 16 and then compute the square root of that value. So the first evaluation gives a 4 and this gets evaluated by sqrt to give the final answer of 2.

Use one line of code to compute the log, to the base 10, of the square root of 100.
Make sure your code includes the log10 and sqrt functions.
