Find the distance

Find the distance between the complex numbers in the complex plane

d = 15

Calculate

18, 3

Any real number can be written as a complex number with the imaginary part 0

18 + 0 \times i, 3

Any real number can be written as a complex number with the imaginary part 0

18 + 0 \times i, 3 + 0 \times i

The complex number for a+bi can be represented as an ordered pair (a,b)

(18, 0), (3, 0)

The distance between the points (a,b) and (s,t) in the complex plane is d = (s - a)^{2} + (t - b)^{2}

d = (18 - 3)^{2} + (0 - 0)^{2}

Solution

More Steps

Calculate

(18 - 3)^{2} + (0 - 0)^{2}

Subtract the numbers

1 5^{2} + (0 - 0)^{2}

Subtract the terms

1 5^{2} + 0^{2}

Calculate

1 5^{2} + 0

Add the numbers

More Steps

Evaluate

1 5^{2} + 0

Removing 0 doesn't change the value,so remove it from the expression

Midpoint

$Find the midpoint between 18 and 3$

Midpoint = (\frac{21}{2}, 0)

Calculate

18, 3

Any real number can be written as a complex number with the imaginary part 0

18 + 0 \times i, 3

Any real number can be written as a complex number with the imaginary part 0

18 + 0 \times i, 3 + 0 \times i

The complex number for a+bi can be represented as an ordered pair (a,b)

(18, 0), (3, 0)

The midpoint between the points (a,b) and (s,t) in the complex plane is Midpoint= (\frac{a + s}{2}, \frac{b + t}{2})

Midpoint = (\frac{18 + 3}{2}, \frac{0 + 0}{2})

Calculate

Midpoint = (\frac{21}{2}, \frac{0 + 0}{2})

Solution

More Steps

Calculate

\frac{0 + 0}{2}

Removing 0 doesn't change the value,so remove it from the expression

\frac{0}{2}

Divide the terms
