(2 + 4i) - (7 + 4i) = -5 2 + 4i - 7 + 4i = -5 + 8i
The two square roots of i are (k, k) and (-k, -k) where k = sqrt(2)/2 = 1/sqrt(2).
The square roots of 4 are -2 and 2.
square inches do not have square roots only number have square roots.
All prime numbers have irrational number square roots, so if you try to find the square root of a non-perfect square number use them to simplify it. For example, ±√125 = ±√25*5 = ±5√5 (when you want to show both the square roots) √72 = √36*2 = 6√2 √-27 = √-9*3 = 3i√3
(2 + 4i) - (7 + 4i) = -5 2 + 4i - 7 + 4i = -5 + 8i
yaa but im tryna find out why
There are no real numbers possible for this combination. Since the quadratic eqn x^2+8x+32=0 have only complex value as their roots. The roots are (-4-4i) and (-4+4i)
The two square roots of i are (k, k) and (-k, -k) where k = sqrt(2)/2 = 1/sqrt(2).

4i(-2 -3i) = 4i×-2 - 4i×-3i = -8i -12i² = -8i + 12 = 12 -8i → the conjugate is 12 + 8i
2ii stands for imaginary, and any negative number's square root is an i number- i, 2i, 3i, 4i, etc.

The two square roots are +70 and -70 .
The two square roots of 18 are: 4.242641 and -4.242641
+6 and -6 are the square roots of 36.
