By applying the conjugate.
e.g.
6 / sqrt(2) = (6sqrt(2)) / (sqrt(2)*sqrt(2)) =>
(6sqrt(2)/ 2=>
3sqrt(2) The answer.
Or a more complex calculation.
( 6 - sqrt(5)) / (2 - sqrt(3))
The conjugate is 2 + sqrt(3) ; Apply top and bottom.
(6 - sqrt(5))(2 + sqrt(3)) / (2 - sqrt(5))(2 + sqrt(5))
We now use FOIL (Like multiplying two brackets together) .
(12 -2sqrt(5) + 6 sqrt(3) - sqrt(15)) / (4 - 2sqrt(5) + 2 sqrt(5) - 5) (
12 -2sqrt(5) + 6 sqrt(3) - sqrt(15)) / ( - 1)
-12 + 2sqrt(5) - 6qrt3) + sqrt(15) This cannot be taken any further!!!!
Hope that helps with division of radicals.
A radical is an exponent, stupid.
If the value applied in the radical is not a perfect square, it is irrational. 25; 400; and 625 are perfect squares and are rational when applied in a radical.
radical(14)*radical(2) = 2*radical(7) Without further information available we will consider only the square roots. The square roots of 14 are +3.741 and -3.741, similarly the square roots of 2 are+1.414 and -1.414 and so we can have four products 1) (+3.741) X (+1.414) = +5.155 2) (-3.741) x (+1.414) = -5.155 3) (+3.741) x (-1.414) = -5.155 4) (-3.741) x (-1.414) = +5.155 Expressions 1 and 4 are equal, expressions 2 and 3 are equal. Hence the product of radical 14 times radical 2 can be +5.155 or -5.155
sqrt(216)factor under the radical by dividing by squared numbers. 6 works.sqrt(62 * 6)bring out 6 from under radical6sqrt(6)===========simplified
Introduces the student to the fundamental concepts of algebra. Topics include the following types of expressions and equations: linear, rational, and radical. Other topics covered include exponents, functions and factoring
A radical is an exponent, stupid.
Radical expressions are called like radical expressionsif the indexes are the same and the radicands are identical.
Why is it important to simplify radical expressions before adding or subtracting? How is adding radical expressions similar to adding polynomial expressions? How is it different? Provide a radical expression for your classmates to simplify..
No. Radical(9) is +3 or -3, both of which are rational.
A rational expression is an expression that contains a radical, i.e., a root.
A radical expression is an expression that involves a square root, cubic root, etc.

If the value applied in the radical is not a perfect square, it is irrational. 25; 400; and 625 are perfect squares and are rational when applied in a radical.
A radical number is a number with a decimal. so a radical expression would be like 5 raised to the 2.5 power.
Radical expressions are applied in one's daily life. This is used in terms of doing tile work, estimating distances, or designing something that needs measurement.
The radical must be identical like the expression must be identical. 2x^2+3x^2=5x^2 notice the power and bases are the same.
It's the second...no hang on, it's the first...I could be wrong, but it might be the third... It looks like my psychic abilities are failing me again, you'll have to list the radical expressions before I can answer for certain.
