Simplify (10-2i)/i

$\frac{10 - 2 i}{i}$

Step 1

Multiply the numerator and denominator of $\frac{10 - 2 i}{i}$ by the conjugate of $i$ to make the denominator real.

$\frac{10 - 2 i}{i} \cdot \frac{i}{i}$

Step 2

Multiply.

Combine.

$\frac{(10 - 2 i) i}{i i}$

Simplify the numerator.

Apply the distributive property.

$\frac{10 i - 2 i i}{i i}$

Multiply $- 2 i i$ .

Raise $i$ to the power of $1$ .

$\frac{10 i - 2 (i^{1} i)}{i i}$

Raise $i$ to the power of $1$ .

$\frac{10 i - 2 (i^{1} i^{1})}{i i}$

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$\frac{10 i - 2 i^{1 + 1}}{i i}$

Add $1$ and $1$ .

$\frac{10 i - 2 i^{2}}{i i}$

Simplify each term.

Rewrite $i^{2}$ as $- 1$ .

$\frac{10 i - 2 \cdot - 1}{i i}$

Multiply $- 2$ by $- 1$ .

$\frac{10 i + 2}{i i}$

Reorder $10 i$ and $2$ .

$\frac{2 + 10 i}{i i}$

Simplify the denominator.

Raise $i$ to the power of $1$ .

$\frac{2 + 10 i}{i^{1} i}$

Raise $i$ to the power of $1$ .

$\frac{2 + 10 i}{i^{1} i^{1}}$

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$\frac{2 + 10 i}{i^{1 + 1}}$

Add $1$ and $1$ .

$\frac{2 + 10 i}{i^{2}}$

Rewrite $i^{2}$ as $- 1$ .

$\frac{2 + 10 i}{- 1}$

Step 3

Simplify the expression.

Move the negative one from the denominator of $\frac{2 + 10 i}{- 1}$ .

$- 1 \cdot (2 + 10 i)$

Rewrite $- 1 \cdot (2 + 10 i)$ as $- (2 + 10 i)$ .

$- (2 + 10 i)$

Step 4

Apply the distributive property.

$- 1 \cdot 2 - (10 i)$

Step 5

Multiply.

Multiply $- 1$ by $2$ .

$- 2 - (10 i)$

Multiply $10$ by $- 1$ .

$- 2 - 10 i$

Simplify (10-2i)/i
