​

Answer 1

The sum of 3√7 and 5√7 is 8√ 7

Step-by-step explanation:

3√7 + 5√7 = 8√7

now my further calculation we got 2.64575131 which non terminating as well as non repeating

hence, we can say it is an irrational no.

then when we will do 8×√7 we will get

=21.1660105

which is an irrational no.
