Question

Which of the following equations represents the greatest value of x?

Equation 1
x² = 24
Equation 2
x^3 = 64
Equation 3
x^2 = 28
Equation 4
x^3 = 125

Equation 1
Equation 2
Equation 3
Equation 4

Answer 1

• Equation 3

Explanation:

Equation 1

• x² = 24 ⇒ x = √24 ⇒ 4 < x < 5

Equation 2

• x³ = 64 ⇒ x = 4

Equation 3

• x² = 28 ⇒ x = √28 ⇒ 5 < x < 6

Equation 4

• x³ = 125 ⇒ x = 5

Equation 3 has the greatest value of x
