Understanding Perfect Squares and Square Roots
In mathematics, a perfect square is a number that can be expressed as the square of an integer. For example, 4 is a perfect square because it can be expressed as 2^2. On the other hand, a square root is a mathematical operation that finds the number that, when multiplied by itself, gives a specified value. For instance, the square root of 16 is 4 because 4 multiplied by 4 equals 16.
When dealing with square roots, it's essential to understand how to remove perfect squares from inside the square root. This process involves factoring the number inside the square root into its prime factors and then simplifying the expression.
Factoring the Number Inside the Square Root
To remove perfect squares from inside the square root, we need to factor the number inside the square root into its prime factors. The number inside the square root is 56z^7. To factor this number, we can start by breaking it down into its prime factors.
56z^7 = 2^3 \cdot 7 \cdot z^7
Removing Perfect Squares
Now that we have factored the number inside the square root, we can remove the perfect squares. In this case, the perfect square is 2^2, which can be expressed as (22)2. We can remove this perfect square by dividing it out of the expression.
\sqrt{56z^7} = \sqrt{2^3 \cdot 7 \cdot z^7} = \sqrt{(2^2)^2 \cdot 2 \cdot 7 \cdot z^7}
Simplifying the Expression
Now that we have removed the perfect square, we can simplify the expression. We can do this by taking the square root of the perfect square and then multiplying the remaining factors.
\sqrt{(2^2)^2 \cdot 2 \cdot 7 \cdot z^7} = 2^2 \cdot \sqrt{2 \cdot 7 \cdot z^7}
Final Expression
The final expression is 4√(14z^7).
Example
Let's consider an example to illustrate the process of removing perfect squares from inside the square root. Suppose we have the expression √(100x^5). To remove the perfect square, we can factor the number inside the square root into its prime factors.
\sqrt{100x^5} = \sqrt{2^2 \cdot 5^2 \cdot x^4 \cdot x}
Now that we have factored the number inside the square root, we can remove the perfect squares. In this case, the perfect squares are 2^2 and 5^2, which can be expressed as (22)2 and (52)2. We can remove these perfect squares by dividing them out of the expression.
\sqrt{2^2 \cdot 5^2 \cdot x^4 \cdot x} = \sqrt{(2^2)^2 \cdot (5^2)^2 \cdot x^4 \cdot x}
Now that we have removed the perfect squares, we can simplify the expression. We can do this by taking the square root of the perfect squares and then multiplying the remaining factors.
\sqrt{(2^2)^2 \cdot (5^2)^2 \cdot x^4 \cdot x} = 2^2 \cdot 5^2 \cdot x^2 \cdot \sqrt{x}
The final expression is 100x^2√x.
