What is the √2 Divided by 2?

Simplifying expressions containing radicals and fractions relies on correctly applying order of operations rules and properties of radicals. Combining radical and fraction operations introduces additional steps compared to expressions with just radicals or just fractions. In this post, we’ll evaluate the expression √2/2, explaining how to simplify radicals with fractions systematically. We’ll also explore strategies for manipulating more complex radical and fractional expressions.

What is the √2 divided by 2?

The square root of 2 divided by 2, written as √2/2, simplifies to (1/2)√2. It is an irrational number approximately equal to 0.7071067811865476 when rounded to several decimal places. This value is commonly encountered in trigonometry as the sine or cosine of 45 degrees in a right triangle with equal legs.

Here’s a table that shows the value of √2 divided by 2:

Expression	Value
√2 / 2	Approximately 0.7071

So, √2 divided by 2 is approximately equal to 0.7071 when rounded to four decimal places.

Reviewing Radicals and Fractions First, let’s review some key concepts and properties:

• Radicals indicate taking the nth root of a number. Example: √9 = 3.
• Fractions represent division of numerator by denominator. Example: 1/2 = 0.5.
• When simplifying, perform radical operations before fraction operations.
• Radicals can be written as fractional exponents. Example: √x = x^(1/2).

Keeping these rules in mind, let’s evaluate our expression √2/2.

Evaluating √2/2 Step-by-Step

Following proper order:

1. Evaluate radical first: √2/2
2. Write radical as fractional exponent: (2^(1/2))/2
3. Simplify fraction: 2^(1/2) / 2^1
4. Subtract exponents: 2^(1/2 – 1)
5. Simplify: 2^(-1/2)

Therefore, the simplified form is 2^(-1/2).

Explanation of the Steps

• Radicals come before fractions in PEMDAS order.
• Fractional exponents allow combining and simplifying.
• Numerator and denominator exponents can be subtracted.
• Leaving the result as a fractional exponent is the simplified form.

Strategies for Simplifying Radicals and Fractions

Some helpful strategies:

• Memorize order of operations PEMDAS.
• Write radicals as fractional exponents to enable simplification.
• Break each step into chunks using parentheses if needed.
• Double check by evaluating result with calculator.
• Practice essential rules until they become intuitive.
