Essentially, square roots are a mathematical function that finds the value that, when multiplied by itself, produces the original number. Simplifying square roots is a crucial component of working with more complex mathematical concepts and equations.

What is 162?

Before we can discuss the simplified form of the square root of 162, it's essential to understand the number itself. 162 is a composite number that can be factored into 2 x 3² x 3⁴. Factoring the number into its prime components is an essential step in simplifying the square root.

Breaking Down the Factors

When attempting to simplify a square root, it's crucial to factor the number into its prime components. In the case of 162, this would mean breaking down the factors 2, 3², and 3⁴. This step is essential because it allows us to simplify each factor individually and then recombine them.

Simplifying the Factors

After breaking down the factors, we can simplify the square roots using basic rules of exponents. For instance, the square root of 3² is simply 3. Once all the factors have been simplified, they can be recombined using multiplication to create a simplified form of the square root of 162.

Reducing the Square Root

Recombining the simplified factors using multiplication gives us the simplified form of the square root of 162. This would look like √(2 x 3² x 3⁴) = 3√(4 x 9 x 9) = 3 x 3 x 3√4 = 18√4. Although this form is simplified, it still includes a fraction, which can be problematic in some applications.

Rationalizing the Fraction

To overcome the problem of fractions, we can rationalize the fraction by multiplying the numerator and denominator by the same factor. In this case, multiplying by 2 would give the simplified form of 18√4 as 36√2. Rationalizing the fraction provides a more convenient form for some mathematical applications.

sin(75) = sin(45)cos(30) + cos(45)sin(30)

sin(75) = (√2/2)(√3/2) + (√2/2)(1/2)

sin(75) = (√6 + √2)/4

cos(75) = cos(45 + 30)

cos(75) = cos(45)cos(30) - sin(45)sin(30)

cos(75) = (√2/2)(√3/2) - (√2/2)(1/2)

cos(75) = (√6 - √2)/4

Once again, the square root of 162 appears in the simplified form of these calculations.
