Find the value of x and y if 2x + ( 3 x + y) i = 4 + 10 i
x = 4, y = 2
x = 2, y = 4
x = 4, y = 3
x = 3, y = 2
Simplify ( 1+ i ) -1
If 2x + (3x + y)i = 4 + 10i, then the value of x and y are
2, 3
2, 4
4, 2
3, 2
The multiplicative inverse of 2+2i is
1/2 - 1/2 i
1/4 - 1/4 i
1/2 - 1/4 i
1/4 - 1/2 i
Determine x and y for which 2x + 3yi = 2+ 9i
x = 1, y = 3
x = 3, y = 1
x = 2, y = 1
x = 1, y = 2
Express in the form b or bi, where b is a real number.
2(√5 + √3)
√5 + √3
2(√5 - √3)
2(√5+√3)i
Write 1 + i2 + i4 + i6 in the form x+ iy
0 + i
