Note the following points:
If a number "a" is positive, and the nth root, n, is even, then there are two nth real roots
If a number "a" is positive and the nth root, n, is odd, then there is just one nth real roots
If a number "a" is negative and the nth root, n, is even, then there are zero nth real roots
If a number "a" is negative and the nth root, n, is odd, then is only one real nth roots
Answers:
Let us match the statements now:
If n is even and a > 0, a has two nth real roots/solutions (g)
If n is odd and a > 0, a has one nth real root/solution (c)
If n is is odd and a < 0, a has one nth real solution (i)
If n is even and a < 0, a has zero nth real solution (f)
