Match each power of i with its multiplicative inverse.
erastovalidia [21]

By definition we have to:
 In mathematics, the inverse multiplicative, reciprocal or inverse of a non-zero number x, is the number, denoted as 1/x or x -1, which multiplied by x gives 1.
 We have then:

 1) i
 The multiplicative inverse is:
 \frac{1}{i}
 Rewriting we have:
 \frac{1}{i} \frac{i}{i}
 \frac{i}{i^2}
 \frac{i}{-1}
 -i
 Answer 3) -i

 2) i^2
 The multiplicative inverse is:
 \frac{1}{i^2}
 Rewriting we have:
 \frac{1}{-1}
 -1
 Answer 4) -1

 3) i^3
 The multiplicative inverse is:
 \frac{1}{i^3}
 Rewriting we have:
 \frac{1}{i*i^2}
 \frac{1}{i^2}*\frac{1}{i}
 \frac{1}{-1}*\frac{1}{i}*\frac{i}{i}
 (-1)*\frac{i}{i^2}
 (-1)* \frac{i}{-1}
 i
 Answer 1) i

 4) i^4
 The multiplicative inverse is:
 \frac{1}{i^4}
 Rewriting we have:
 \frac{1}{i^2i^2}
 \frac{1}{(-1)(-1)}
 \frac{1}{1}
 1
 Answer 2) 1
