Question

conjugate of complex number 5-i(6-i)

Answer 1

The conjuagte of 4-6i is 4+6i

Explanation:

Given:

complex number 5-i(6-i)

To find:

The Conjugate of complex number 5-i(6-i)

==> Evaluate the given question in the form a+ib

==> So, that we can conjugate the complex number

==>  5-i(6-i)

==> Multiply i in the equation

==> 5-6i+i²

==> We know that, i²=-1

==> 5-6i-1

==> 4-6i

==> This is in the form of a+ib

==> Taking conjugate 4-6i

==> The conjuagte of a+ib is a-ib

==> The conjuagte of 4-6i is 4+6i
