## How do you calculate square root?

Example: Calculate the square root of 10 ( ) to 2 decimal places.

- Find the two perfect square numbers it lies between. Solution: 3
^{2}= 9 and 4^{2}= 16, so lies between 3 and 4. - Divide 10 by 3. 10/3 = 3.33 (you can round off your answer)
- Average 3.33 and 3. ( 3.33 + 3)/2 = 3.1667.

## What is the square root of 45 rounded to the nearest whole number?

6.71 is the answer that I came up with.

## What are the factors of 45?

So in list form, the 45 factors are 1, 3, 5, 9, 15, and 45.

## Is Root 45 a SURD?

Answer. Therefore, √20 × √ 45 is a rational number.

## IS 400 a perfect square?

400 is a perfect square. Because 20 * 20 = 400.

## How do you find the root value?

The product property of square roots states that for any given numbers a and b, Sqrt (a × b) = Sqrt (a) × Sqrt (b). Because of this property, we can now take the square roots of our perfect square factors and multiply them together to get our answer. In our example, we would take the square roots of 25 and 16.

## What is the square root of 47 simplified?

The square root of 47 cannot be simplified. √ 47 is already in its simplest radical form. If you are using a computer that has Excel or Numbers, then you can enter SQRT ( 47 ) in a cell to get the square root of 47. Below is the result we got with 13 decimals.

## Is 45 an irrational number?

45 is not an irrational number because it can be expressed as the quotient of two integers: 45 ÷ 1.

## What is the square root of 32 simplified?

1 Answer. The answer is 4√2.

## How do you simplify?

To simplify any algebraic expression, the following are the basic rules and steps:

- Remove any grouping symbol such as brackets and parentheses by multiplying factors.
- Use the exponent rule to remove grouping if the terms are containing exponents.
- Combine the like terms by addition or subtraction.
- Combine the constants.

## How do you solve root problems?

Steps

- Square a number by multiplying it by itself.
- For square roots, find the “reverse” of a square.
- Know the difference between perfect and imperfect squares.
- Memorize the first 10-12 perfect squares.
- Simplify square roots by removing perfect squares when possible.
