How do you solve square roots examples?

For example, 5 and – 5 are both square roots of 25 because: 5 x 5 = 25 and -5 x -5 =25. The square root of a number x is denoted with a radical sign √x or x 1/2. For instance, the square root of 16 is presented as: √16 = 4. Repeated Subtraction.

25 -1 = 24
21 -5 = 16
16 – 7 = 9
9 – 9 = 0

What are the four steps to solve a square root equation?

Follow the following four steps to solve radical equations.

  • Isolate the radical expression.
  • Square both sides of the equation: If x = y then x2 = y2.
  • Once the radical is removed, solve for the unknown.
  • Check all answers.

Why is 9 The square root of 81?

Explanation: 81 = 9 ⋅ 9 then the square root of √ 81 = 9. Because the double multiplication for the same sign is always positive, the square root is also valid with the other sign 81 =(− 9 )⋅(− 9 ) then √ 81 =− 9 and we can say that √ 81 =± 9.
