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.

Instructions

100 XP
  • 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.
