## 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 x
^{2}= y^{2}. - Once the radical is removed, solve for the unknown.
- Check all answers.

## What is the formula of square root?

The two square numbers in between which;3′ lies are 1 and 4. So, the square root of 3 lies between 1 and 2. Find the average of these two numbers to get the square root of 3. Square root of 3 = (1.5 + 2)/2 = 1.75 which is approximately equal to square root of 3. Square Root Formulas with Examples.

## What is the solution of sqrt 2x 4 16?

Answer: The solution of the equation is x=126.

## What is 9 The square root of?

The square root of a number is a number that, when multiplied by itself, equals the desired value. So, for example, the square root of 49 is 7 (7×7=49). List of Perfect Squares.

NUMBER | SQUARE | SQUARE ROOT |
---|---|---|

6 | 36 | 2.449 |

7 | 49 | 2.646 |

8 | 64 | 2.828 |

9 | 81 | 3.000 |

## 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.

## Which of the following is an extraneous solution of sqrt 2?

Answer Expert Verified x=8 is a extraneous solution.

## Which of the following is a radical equation sqrt 13?

x+3 = sqrt 13.

## How do you factor equations?

With the quadratic equation in this form:

- Step 1: Find two numbers that multiply to give ac (in other words a times c), and add to give b.
- Step 2: Rewrite the middle with those numbers:
- Step 3: Factor the first two and last two terms separately:
