Simplify the square root of 512?
The idea is to take out perfect squares. The largest perfect square in this case is 256, which is the square of 16 (if you have trouble figuring this out, you can take out a smaller perfect square first, and then see if you find additional perfect squares). In any case, the end result should not have a factor that is a perfect square. Using the symbol "root()" for square root: root(512) = root(256 x 2) = root(256) x root(2) = 16 root(2)
Is the square root of 6 rational?
No; you can prove the square root of any positive number that's not a perfect square is irrational, using a similar method to showing the square root of 2 is irrational.
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 factored form?
the form of an expression compossed of products of factors, rather than sums or differences of terms. the expressions x(x-2) and (x+3)(x+4) are in factored form. y=(x-2)(x+5), or factored form, is an equation that describes a parabola. Once factored, using a FOIL method, it becomes standard form. y=(x-2)(x+5) y=x^2+5x-2x-10 y=x^2+3x-10
