aliya0001 [1]
<span>Exponent is a number used to express shorter equation; it is a number that says how many times you are going to multiply the base number.

Exponents have several laws, here are some:
=> x^1 = x
=> x^0 = 1
=> x^-1 = 1/x
=> x^m x^n = X^m+n
=> x^m/x^n = x^m-n

Advocard [28]

So, S(Mon) = 1

S(Tues) = 2

S(Wed) = 3

S(Thurs) = 4

S(Fri) = 0

Hence, S^{- 1}(0) = Friday
