add simplify by collecting like radical terms if possible assuming that all expressions under radicals represent nonnegative numbers
ã2a+5ã8a^3
i have the answer as (1+10a)squareroot symbol 2a is this correct?

math 
Reiny,
I will assume you mean
√(2a) + 5√(8a^3)
= √(2a) + 5√( (2a)^3)
= √(2a) + 5(2a)√(2a)
= 11√(2a) or 11√2 √a
