add simplify by collecting like radical terms if possible assuming that all expressions under radicals represent nonnegative numbers

ã2a+5ã8a^3

i have the answer as (1+10a)squareroot symbol 2a is this correct?

  • math -

    I will assume you mean

    √(2a) + 5√(8a^3)

    = √(2a) + 5√( (2a)^3)
    = √(2a) + 5(2a)√(2a)
    = 11√(2a) or 11√2 √a
