= 335

Solution:

Concept:

Solve the equation by isolating the square root and then squaring both sides.

Explanation:

Write the given equation:

\sqrt{?} + 17^{2} = 335

Calculate

17^{2} = 289

So,

\sqrt{?} + 289 = 335

Subtract

289

from both sides:

\sqrt{?} = 335 - 289 = 46

Square both sides to find

?

? = 46^{2} = 2116

Answer:

The required value is

2116
