Solve 7/i

$$\frac { 7 } { i }$$

Evaluate

$$-7i$$

Solution Steps

Multiply both numerator and denominator by imaginary unit i.

$$\frac{7i}{1i^{2}}$$

By definition, i^{2} is -1. Calculate the denominator.

$$\frac{7i}{-1}$$

Divide 7i by -1 to get -7i.

$$-7i$$

Real Part

$$0$$

Solution Steps

Multiply both numerator and denominator of \frac{7}{i} by imaginary unit i.

$$Re(\frac{7i}{1i^{2}})$$

By definition, i^{2} is -1. Calculate the denominator.

$$Re(\frac{7i}{-1})$$

Divide 7i by -1 to get -7i.

$$Re(-7i)$$

The real part of -7i is 0.

$$0$$
