Question

$65 + \sqrt{x} = 83$
​

Answer 1

65 + sqrt(x) = 83

sqrt(x) = 83 - 65 = 18

x = 18^2 = 324 ——> Answer

Answer 2

x = 324 if 65 + √x  = 83

Step-by-step explanation:

Given :

65 + √x  = 83

To Find :

Value of x

65 + √x  = 83

Lets subtract 65 from both sides

=> 65 + √x  -65 = 83 - 65

=> √x  = 18

Now Squaring Both sides

=> (√x)² = (18)²

=> x = 18²

18² = (20 - 2)²

= 20² + 2² - 2*20*2

= 400 + 4 - 80

= 324

x = 324
