Answer:
x = 10
Step-by-step explanation:

→ In an equation our aim is to isolate 'x' and find the value and so the first step is to square both sides to get rid of the square root
x² - 36 = 64
→ Add 36 to both sides to isolate x²
x² = 100
→ Square root both sides to isolate x
x = 10
The answer would be the second one, you can immediately cross off the first one and 3rd one, 2 x 200 = 400 - 300 = 100 :)
