8 - 8i
8i and -8i both satisfy this: (8i)² = (8²)(i²) = (64)(-1) = -64, and (-8i)² = (-8²)(i²) = (64)(-1) = -64
x2 - 2x + 65 = 0 Subtract 64 from each side: x2 - 2x + 1 = -64 (x - 1)2 = (i*8)2 where i is the imaginary square root of -1 x - 1 = +/- 8i x = 1 +/- 8i
(2i)3 = 8i3 = 8(i2)(i) = 8(-1)(i) = -8i
80000000 plus 4000000 plus 100 plus 8 in standard form = 84,000,108

If you mean 8i, i might be any variable, but it may also stand for the imaginary unit, sometimes defined as the square root of minus 1. In that case, 8i is 8 times the square root of minus 1.If you mean 8i, i might be any variable, but it may also stand for the imaginary unit, sometimes defined as the square root of minus 1.

Polar form = re^i(angle) r=(4+4)^.5 angle=atan(2/2) PF = (8)^.5*e^atan(1) pf = 2.83e^.7854i

80000000 plus 4000000 plus 100 plus 8 in standard form = 84,000,108
There is a mathematical symbol missing and I am assuming the question to be -2i(8i + 4) - 8(4 - 4i) which is -16i^2 - 8 - 32 - 32i which is -16(-1) - 8 - 32 - 32i which is +16 - 8 - 32 - 32i which is -24 -32i
What is 1,000,000+500,000+8 written in standard form
Numbers of the form a + ib (where i = -11/2; a and b are real numbers) are called complex numbers.For any two complex numbers (a+ib) and (c+id):Addition:(a+ib) + (c+id) = (a+c) + i(b+d)So, -8i-7i = (-8-7)i = -15i
The square root of 64 is +/- 8
8 + 0.8 + 0.07 = 8.87
