There are basically two ways to work out a square root. Either your goal is to find an EXACT, mathematical result, or your goal is to find an ESTIMATED result.
To get an ESTIMATED result, you need to key it into the calculator and round the answer to the specified number of digits for your assignment. Anything else involves using "power series"... something in University level Mathematics.
To get an EXACT result, you need to simplify the expression by square root operators:
sqrt(0.36) = sqrt( 36 / 100 )
Keep simplifying until you have nothing by prime factors in there:
sqrt( 2 x 3 x 2 x 3 / 2 x 5 x 2 x 5 )
Next we can cancel out all the 2s from that fraction:
sqrt( 3 x 3 / 5 x 5 )
Next, we can break the square root:
sqrt( 3 x 3 ) / sqrt( 5 x 5 )
In this case the answer is 3/5.

Square root 2 times square root 3 times square root 8?
square root 2 times square root 3 times square root 8
What is the square root of 4x?
We use the property of square roots that says the square root of (ab)=square root (a) multiplied by square root of b So square root (4x)=square root (4) mutiplies by square root of x =2(square root (x)) 2sqrt(x)
What numbers are always irrational?
the square root of 3, the square root of 5, the square root of 6, the square root of 7, the square root of 8 etc
What is the square root of 75 divided by the square root of 3?
Square root (75) / square root (3) = 5
What is the square root of the square root of 2?
The square root of the square root of 2

Irrational numbers between 2 and 2.5?
There are infinitely many of them. They include square root of (4.41) square root of (4.42) square root of (4.43) square root of (4.44) square root of (4.45) square root of (5.3) square root of (5.762) square root of (6) square root of (6.1) square root of (6.2)
What is the square root of a square that has no root?
It's not a square if it has no root. If a number is a square then, by definition, it MUST have a square root. If it did not it would not be a square.
Square root 2 times square root 3 times square root 8?
square root 2 times square root 3 times square root 8
What is a principal square root?
The principal square root is the non-negative square root.
What is the square root of 4x?
We use the property of square roots that says the square root of (ab)=square root (a) multiplied by square root of b So square root (4x)=square root (4) mutiplies by square root of x =2(square root (x)) 2sqrt(x)
What is the difference between principal square root and perfect square root?
A principal square root is any square root that's answer is positive, and a perfect square root is a square root that's answer is an integer.
What is the square root of 20 in simplest form?
square root of 20 = square root of 4 * square root of 5. square root of 4 = 2, so your answer is 2 square root of 5.
Simplify square root of 5 Times Square root of 6?
Square root of 5 time square root of 6 is the same as square root of 5 x 6, that is, square root of 30.
What numbers are always irrational?
the square root of 3, the square root of 5, the square root of 6, the square root of 7, the square root of 8 etc
