Before √2 there will be 1 so √2+√2=2√2
and √2×√2=2
0
√2 means root 2
no thats not what i mean
when we add root 2 with root 2 we must know tht root 2 means 1rootover 2 we dont thik it is necessary to write the one so its remains invisible most of the times so adding 1 with 1 and taking root 2 as common we get the answe 2root2.
also root 2 multiplies root 2 is 2 because the root over gets cancelled

√2+√2= 2√2 because the no. of √2 is 2 , so 2 is taken in common and one √2 is taken with 2.............. In case of √2×√2, the answer is 2 as when √2 is multiplied with √2 the answer is 2. , so √2×√2= 2....
