# Math-Involing i's

posted by .

1)What is the product of 5+ Radical (-36) and 1-Radical (-49) expressed in simplest a+bi Form?

• Math-Involing i's -

(5 + √-36)(1-√-49)
= (5 + 6i)(1 - 7i)
= 5 - 35i + 6i - 42i^2
= 5 - 29i + 42
= 49 - 29i

2) √-27 + i^22 + 3 - √-25 + 5√-3
= 3√3i + (-1) + 3 - 5i + 5√3i
= 8√3i - 5i + 2
= (8√3 - 5)i + 2
