Answer 2

Answer:

5√3 + 13√5

Step-by-step explanation:

the square roots that cannot be simplified are called surds.

eg: √5 is a surd, but √4 is not surd because √4 can be simplified to 2.

while adding surds, group the numbers with same surd and add the before numbers.

here,

==> (√3+ 7√5) + (4√3 + 6√5)

==> (√3+4√3) + (7√5 + 6√5)

==> 5√3 + 13√5
