Simplify square root of 36x4y2?
If x is a multiplication symbol, then square root of 36(4)y^2 = square root of(4^2)(2^2)(y^2) = (4)(2)(y) = 8y If it is a variable x, then square root of 36x4y^2 = square root of (4^2)(x)(2^2)(y^2) = (4)(2)(y)(square root of x)= 8y(square root of x)
What mathematical symbol can you put between 1 and 2 to make a number greater than 1 but less than 2?
the square root symbol. that would make it 1,/2 (i don't know how to make a square root symbol, sorry) but since the numbers are next to each other it is assumed that they are being multiplied and the square root of 2 is approximately 1.414 right in between 1 and 2 :)

What is the symbol used to denote a root?
The radical symbol √ (with a line over what you're taking a root of) denotes root.The symbol without any other numbers, means square root, while with a number like 3√ means take cube root, 4√ fourth root, etc.If you want to type this symbol in Windows, hold down the key on the keyboard, then type (on the number pad) 251, then let go of the key.You can also denote roots by fractional exponents: 1/2 power is the square root,1/3 power is the cube root, etc and this works if you have an xy (exponentiation)key on your calculator and want to compute roots.The symbol used to make a root is √
