Answer:

x = ± sqrt(k)

x = ± 8 by the square root property

Step-by-step explanation:

x^2 = k

K is a real number

Take the square root of each side

sqrt(x^2) = ± sqrt(k)

x = ± sqrt(k)

Letting k = 64

x = ± sqrt(64)

x = ± 8 by the square root property

Answer:

x = ± √k

x = ± √8 by the square root property

Step-by-step explanation:

x² = k

where k is a real number

square root of each side

√x² = ± √k

x = ± √k

let k = 64

x = ± √64

therefore

x = ± 8 by the square root property
