Question

Which of the following equations represents the greatest value of x? Equation 1 x2 = 17 Equation 2 x2 = 26 Equation 3 x3 = 64 Equation 4 x3 = 27

a. Equation 1
b. Equation 2
c. Equation 3
d. Equation 4

Answer 1

c. equation 3 because x= 30 one third

Answer 2

The greatest value of x is 5.1 from Equation 2 .

Option (b) is correct .

Explanation:

As the equation given in the question.

Equation 1

x² = 17

`x = √(17)`

x = 4.12 (Approx)

Equation 2

x² = 26

`x = √(26)`

x = 5.1 (Approx)

Equation 3

x³ = 64

`x = \sqrt[3]{64}`

x = 4

Equation 4

x³ = 27

`x = \sqrt[3]{27}`

x = 3

Therefore the greatest value of x is 5.1 from Equation 2 .

Option (b) is correct .
