Question

X square =100 solve for X
​

Answer 1

Answer:

10

Step-by-step explanation:

10² = 10*10 = 100

Therefore, √100 = 10

Answer 2

Required Answer:-

Given:

• x² = 100

To Find:

• The values of x.

Answer:

• x = ±10

Solution:

Given that,

→ x² = 100

→ x² - 100 = 0

→ x² - 10x + 10x - 100 = 0

→ x(x - 10) + 10(x - 10) = 0

→ (x + 10)(x - 10) = 0

Therefore,

→ (x + 10) = 0 or (x - 10) = 0

→ x = 10, -10

Alternative Method:

Given,

→ x² = 100

Taking square roots of both sides, we get,

→ √x² = √100

→ x = √(10 × 10)

→ x = ±10

Therefore,

→ x = 10, -10
