If you would like to write <span>(-3 + √-9)^2 in a standard form a + i * b, you can do this using the following steps:
</span>(-3 + √-9)^2 = (-3)^2 - 2 * 3 * √-9 + (<span>√-9)^2 = 9 - 6 * 3 * i - 9 = 0 - 18 * i = -18 * i
</span>
The correct result would be -18 * i.
You are told 1 cm = 45 km
The distance is 2cm
2cm / 1cm = 2
2 x 45 = 90 km
The distance is 90 km.
