Question

2. The square root of a number is 6. Write an equation , using x that represents this situation. Please help.

Answer 1

The equation that represents this situation could be:

• 
  `√(x) = 6`

Explanation:

How the statement says: "The square root of a number is 6", your unknown number is the one that taking the square root you obtain 6, by this, the right equation is:

• 
  `√(x) =6`

Now, we solve this to identify the unknown number:

• 
  `√(x) = 6`

To eliminate the square root, you must elevate to the square root in both places:

• 
  `(√(x))^(2)= 6^(2)`

On the left side, the square root and the square elevated are eliminated, on the right side the number six is elevated to its square:

• 
  `x=36`

So, the value of x makes this equation true is 36.
