Similar radicalssuch as ... 5(sq root 7) + 3(sq root 7)
are similar because the radical has the same root index and the same number inside the radical. Like variables they can have different coefficients. 2x and 5x are similar ( called like terms) add the coefficients.
2x + 5x = 7x similarly
5(sq root 7) + 3(sq root 7) = 8(sq root 7)

To add or subtract radical fractions, you need to have the same radical term in the numerator and denominator. Find a common denominator and then combine the numerators (if adding) or subtract the numerators (if subtracting) while keeping the common denominator. Simplify the resulting fraction, if possible.
Similar fractions are fractions with the same denominator. In order to add or subtract fractions they need to be similar.
similar-a similar radicand is to add or subtract similar radicals we simply add and subtract there coefficients and Anex to the sum of their common radical part.
No, you cannot add or subtract under the radical. The radical represents the square root function, and it only operates on the number or expression that is inside the radical. To add or subtract, you need to simplify the expressions inside the radical first.
Make the fractions equivalent then subtract
no, to add and subtract like and unlike fractions the denominator has to be the same,
