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

2) Express Radical (-27) + i^22 + 3-Radical (-25) +5 Radical (-3) 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
