5 Steps To Simplify Radical 80

Quick Links :

Radical 80, also known as the "reciprocal radical" or "inverse radical," can be a challenging concept for many students to grasp. However, with the right approach, it can be simplified and made more manageable. In this article, we will explore the 5 steps to simplify radical 80.

What is Radical 80?

Before we dive into the steps to simplify radical 80, let's first understand what it is. Radical 80 is a mathematical expression that represents the square root of 80. It is denoted by the symbol √80.

Step 1: Factor Out Perfect Squares

The first step to simplify radical 80 is to factor out perfect squares. A perfect square is a number that can be expressed as the square of an integer. In this case, we can factor out 16, which is a perfect square.

80 = 16 × 5

Step 2: Simplify the Radical

Now that we have factored out the perfect square, we can simplify the radical. We can rewrite the expression as:

√80 = √(16 × 5)

Using the property of radicals that states √(ab) = √a × √b, we can simplify further:

√80 = √16 × √5

Step 3: Simplify the Square Root of 16

The square root of 16 is a perfect square, which means it can be simplified further. The square root of 16 is equal to 4.

√16 = 4

So, we can substitute this value back into our expression:

√80 = 4 × √5

Step 4: Rationalize the Denominator

If we were to leave the expression as is, it would be in a form that is not commonly used. To rationalize the denominator, we can multiply the numerator and denominator by √5.

√80 = 4 × √5 = (4 × √5) / (√5 × √5)

Using the property of radicals that states √(a × a) = a, we can simplify further:

√80 = (4 × √5) / 5

Step 5: Write the Final Answer

Now that we have simplified the radical, we can write the final answer.

√80 = 4√5 / 5

And that's it! We have successfully simplified radical 80.

Conclusion

Simplifying radical 80 can seem daunting at first, but by following these 5 steps, you can break it down into manageable parts. Remember to factor out perfect squares, simplify the radical, simplify the square root of 16, rationalize the denominator, and write the final answer. With practice, you'll become more comfortable simplifying radicals and tackling more complex math problems.
