The Answer should be twenty eight 28
Answer:
Step-by-step explanation:
solve the quadratic equation
x² + 164 = 16x
x² - 16x + 164 = 0
quadratic formula
x = (16 ±√((-16)² - 4(1)(164))) / (2(1))
x = (16 ± √-400) / 2
x = (16 ± 20√-1) / 2
x = 8 ± 10√-1
as √-1 = i, the zeros are
x = 8 + 10i
x = 8 - 10i
A perfect cube is a cube that reduces "perfectly" without any decimals. Examples include √25 = 5
√100=10
