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
What is the square root of 304?
The square root of 304 is approximately 17.4642491965. This can be calculated by finding the prime factorization of 304, which is 2^3 * 19, and then simplifying the square root expression. The square root of 304 can also be expressed as 2√76 or 4√19 in simplified radical form.
What is the square root of 64 over 4?
The square root of 64/4 = 4
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 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)
