Exercises

1. Write a function to raise to any power. You don’t just want to square numbers, you want to raise them to higher powers too. Make a function that uses two arguments, x for a number, and power for the power. Call it raise().

raise <- function() {
  
}

# test with
raise(x = 2, power = 4)
# should give you
2^4

2. Change your raise() function to default to squaring x when the user doesn’t enter a value for power.

# test
raise(x = 5)
# should give you
5^2
