Here are a few examples of radical no.
sqrt 64 = sqrt (8^2) = 8
sqrt 69 = there's no easy way to do this by hand because there are no perfect squares that are factors of 69. So, either you leave it as "sqrt 69" or you use a calculator to figure it out.
sqrt 128
= sqrt (64*2)
= sqrt (8^2 * 2)
= sqrt 8^2 * sqrt 2
= 8 sqrt 2
That's as far as you can simplify that one by hand. If you need an actual number, you have to calculate sqrt 2 using a calculator, then multiply it by 8. Hope I help you :)

What does 3 radical 2 plus 4 radical 2 equal?
first the two numbers have the same radicand which is radical 2 so we just add the numbers before them to become 7 radical 2
What role do radical numbers play in your current or future profession?
The role that radical numbers play in your profession depend on what profession you are in. Careers in science and engineering use radical numbers in various ways including to prove concepts and to calculate limits and dimensions.
When you multiply a radical number with another radical number do the radical signs cancel each other out?
Not necessarily. If it is the same radical number, then the signs cancel out. Radical 5 times radical 5 equals 5. But if they are different, then you multiply the numbers and leave them under the radical sign. Example: radical 5 * radical 6 = radical 30
How do you evaluate a radical?
There are three steps on how to evaluate a radical. Some of the step-by-step instructions are multiply two radicals with the same index number by simply multiplying the numbers beneath the radicals, divide a radical by another radical with the same index number by simply dividing the numbers inside, and simplify large radicals using the product and quotient rules of radicals.
Are all irrational numbers radical?
No they are not. The numbers Pi and e are irrational and are not radicals. There are many others.
