The area of the rectangle given below is less than 60.5 square centimeters. what is the width of the rectangle? estimate the width of the rectangle first, and then determine whether your solution is reasonable.

You could guess a bit:  let L be the length and W be the width.  Then L*W=60.5 square centimeters.  Solving for the width, W, W=60.5 sq. cm. - L

D. i

Step-by-step explanation:

When putting i to a power, there is a rule.

i¹ = i

i² = -1

i³ = -i

i⁴ = 1

And it repeats again, such as:

i⁵ = i

i⁶ = -1

And so forth.

This rule also applies to -i, but the values are slightly different:

(-i)¹ = -i

(-i)² = -1

(-i)³ = i

(-i)⁴ = 1

And that one keeps repeating such as

(-i)⁵ = -i

(-i)⁶ = -1

And so forth.

So to answer your question, (-i)³ = i.
