All right, let's say that you have an equation like this:
2x=4
In order to find x, we need to get it alone. Because of this, we will divide by 2. The reason we divide by 2 is because when you're trying to get the answer of something in Algebra, you will need to do the opposite of what is being done to the original variable.
The same is true with a square root.
they cancel each other out. the square root of 5 raised to the second power = 5
Yes, the whole idea of taking the "square root" of a number is, for example for the square root of 2, to find the number that, when squared, gives you 2. if you try to do both, they cancel each other out.
(√(a))²=a The square root and the square cancel to leave just 49/21■
The power and the root cancel each other out and the result is the radicand (the number under the radical sign).
Find the factors of 89. Then put cancel out all of the factors that are perfect squares and put them outside of the root. Multiply the remaining factors under the root.
Yes. Root two squared= two. Squares and roots cancel each other out.
they cancel each other out. the square root of 5 raised to the second power = 5
Yes, the whole idea of taking the "square root" of a number is, for example for the square root of 2, to find the number that, when squared, gives you 2. if you try to do both, they cancel each other out.
The square root of pi times pi is simply pi. Because pi*pi=pi squared, the squared and the square root will cancel each other, leaving just pi.
√(16x16) = √(162), and since the square and square root cancel, the square root of 16x16 is 16.
(√(a))²=a The square root and the square cancel to leave just 49/21■
yes
The square root of 2 squared is 2. sqrt(22)=2 The square root function and the exponent 2 and opposite function and cancel each other out. 22=4 sqrt(4)=2 =>sqrt(22)=2 What is the (square root of 2) squared - If you take the square root of a number then square it the answer is the number itself, so the answer is 2! What is the square root of (2 squared) - Looking at the question another way, if you take a number and square it, the square root of the resulting answer is the number itself, so the answer is 2! Unless, of course, this is a trick question . . . ivj
b over the square root of 5 The square root of 5b squared is 5b, and the simplified form of the square root of 125 is 5 root 5. The 5s then cancel out leaving b over the square root of 5.
The power and the root cancel each other out and the result is the radicand (the number under the radical sign).
They are inverse functions of each other.
Find the factors of 89. Then put cancel out all of the factors that are perfect squares and put them outside of the root. Multiply the remaining factors under the root.
