What is the simplest radical from of the square root of 84?
First note that 84=4x21 and 4 is a perfect square. So square root of (84)=square root (4x21)=Square root (4) Square root (21)= 2 multiplied by the square root of 21. You can also write this using rational exponents, but this is not in radical form. It is an equivalent expression, however. 2 x (21)1/2
How do you find the square roots?
There is normally a square root button on your calculator The square root of a number is a number times itself. Most square roots are memorized, such as the square root of 16 being four. The easiest way to find a square root is using the root function on a calculator. you find the square route by thinking what times this number equals this number. For example.... the square route of 64 is 8 because 8x8 equals 64. Basically the same number times itself. Another example 12x12=144 notice the factors are the same.
What is the square root of 64 over 4?
The square root of 64/4 = 4
What is the square root of negative 4?
That greatly depends on what level of math you are taking. Early math classes might want you to say, "You can't take the square root of a negative number." Later math will talk about real numbers and still the answer would be, "The square root of -4 does not have a real answer." Still later in your math career you will see imaginary numbers whereby the special character "i" is equivalent the the square root of -1. If imaginary answers are allowed, then the square root of -4 = 2i (since -4 is the same as -1 x 4, the square root of -1 x 4 = i x 2 =2i)
Which expression gives the distance the points (1 -2) and (2 4)?
square root of (5-9)^2+(1+6)^2

What is the square root of minus 4?
The answer is 2i. When dealing with negative square roots, the expression i is used to represent the square root of -1.
What is equivalent to 4 to the square root of 3?
6.92820323
How do you solve 4 square root 6 plus 3 square root 2 minus 2 square root 5?
Multiply the entire expression by a least common multiple and then simplify the expression. In this case, the least common multiple is 30 so multiply the entire expression by 30 and simplify.
What is the value of the expression square root of 56 divided by the square root of 14?
4
What is the square root of 2x squared?
4
What is the simplified expression of the square root of 3 4?
sqrt(3/4) = sqrt(3)/2
Simplify the expression 2 square root 3 multiply square root 12?
hmm... okay, if I understand you correctly, 2 times the square root of 3 times the square root of 12? = 2(1.73)(3.46) = 11.9716. If you aren't using the approximations, then just simplifying is... [sorry, I can't do the square root sign on the computer...] 2(square root of 3)(square root of 12) = 2(square root of 3)(square root of 4*3) = 4(square root of 3)(square root of 3) = 4(3) = 12!!! HOPE I HELPED!! :-)
What is 4 square root?

What is the square root of 8 as a decimal?
The square root of 8 is an irrational number and so can only be represented by an infinitely long decimal expression. Rounded to 4 decimal places, it is 2.8284
