Answer:
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 = 4.12 (Approx)
Equation 2
x² = 26

x = 5.1 (Approx)
Equation 3
x³ = 64
![x = \sqrt[3]{64}](https://img.qammunity.org/2016/formulas/mathematics/high-school/x3ucbwhde3ic5oqm1upkz9mtszrdjaqcua.png)
x = 4
Equation 4
x³ = 27
![x = \sqrt[3]{27}](https://img.qammunity.org/2016/formulas/mathematics/high-school/wa0i1vpm42qt6rd8ipk8wggg51c782ljyj.png)
x = 3
Therefore the greatest value of x is 5.1 from Equation 2 .
Option (b) is correct .
