Answer:z=1+0i (rectangular coordinate)
z=cos0+sin0 or exp^i0 (polar coordinate)
Step-by-step explanation:
Unity is 1
Let z be a complex number
z =√1
z=1
z = x + iy(rectangular coordinate)
z=rcos(theta)+isin(theta) (polar coordinate)
For rectangular form, since unity is a real value, x=1 and y=0(no complex value)
z=1+0i (rectangular)
For polar, we need to calculate 'r' and theta.
r=√x^2+y^2
r=√1+0
r=1
theta= arctan(y/x) = arctan(0/1) = 0degree.
z=cos0+sin0 or exp^i0
Answer:
Step-by-step explanation:
A repeating or recurring decimal is decimal representation of a number whose digits are periodic and the infinitely repeated portion is not zero. It can be shown that a number is rational if and only if its decimal representation is repeating or terminating. An example is 0.666...

Step-by-step explanation:
7x²(6x + 3x² - 4)
7x² × 6x = 42x³
7x² × 3x² = 21x⁴
7x² × -4 = -28x²
42x³ + 21x⁴ - 28x² is the correct answer.
