Type your math problem... p = (1 i)7 (1 - i)7

x

Question

Solve the equation

p = 49 + 49 i

Evaluate

p = (1 \times i) \times 7 (1 - i) \times 7

Remove the parentheses

p = 1 \times i \times 7 (1 - i) \times 7

Solution

More Steps

Evaluate

1 \times i \times 7 (1 - i) \times 7

Rewrite the expression

i \times 7 (1 - i) \times 7

Multiply the terms

i \times 49 (1 - i)

Multiply the numbers

49 i (1 - i)

Apply the distributive property

49 i + 49 i (- i)

Multiply the numbers

More Steps

Evaluate

49 i (- i)

Multiply

49 (- 1) i^{2}

Multiply

- 49 i^{2}

Use i^{2} = - 1 to transform the expression

- 49 (- 1)

Calculate

49

49 i + 49

Reorder the terms

49 + 49 i

p = 49 + 49 i
