Question

Two surds can be added if their bases as well as _________ are same *​

Answer 1

Answer:

Adding and subtracting surds The rule for adding and subtracting surds is that the numbers inside the square roots must be the same. Example 5 2 − 3 2 = 2 2 This is just like collecting like terms in an expression . 4 2 + 3 3 cannot be added since the numbers inside the square roots, are not the same.
