Your starting expression looks like this. √2 +√6. Now, because the square root terms are different, you can't really add these two radicals. However, you could simplify this expression a bit. Notice that you can write 6 as. 6 = 2 ⋅ 3. This means that you have. √2 +√2 ⋅ 3 = √2 + √2 ⋅ √3. Now use √2 as a common factor to get.

How do you simplify radical expressions? There are two common ways to simplify radical expressions, depending on the denominator. Using the identities #\sqrt {a}^2=a# and # (a-b) (a+b)=a^2-b^2#, in fact, you can get rid of the roots at the denominator. Case 1: the denominator consists of a single root. For example, let's say that our fraction ...

When you have a root (square root for example) in the denominator of a fraction you can"remove" it multiplying and dividing the fraction for the same quantity. The idea is to avoid an irrational number in the denominator. Consider: #3/sqrt2#. you can remove the square root multiplying and dividing by #sqrt2#; #3/sqrt2*sqrt2/sqrt2#.

The square root pf a number can be simplified only if the number is divisible by a perfect square (other than 1). sqrt12 can be simplified because 12 is divisible by 4 -- a perfect square. sqrt12 = sqrt(4xx3) = sqrt4xxsqrt3=2sqrt3 sqrt250 can be simplified because 250 is divisible by 25 sqrt250 = sqrt(25xx10)=sqrt25xxsqrt10=5sqrt10 But 6 is not divisible by a perfect square, so sqrt6 cannt be ...

Explanation: Negative numbers have no real square roots, so I assume that you are working with imaginary numbers. =sqrt (6) i Negative numbers have no real square roots, so I assume that you are working with imaginary numbers. Using the property of imaginary numbers that i^2=-1 we can right the question as: sqrt (6i^2) =sqrt (6) i.

Guess what the square root of the irrational number is. For example, if your irrational number is 2, you might guess 1.2. Divide the initial irrational number by the guessed number. For example, 2 divided by 1.2 is 1.67. Add the resulting sum to the original guessed number. For example, 1.67 plus 1.2 is 2.87.
