Simplify:
sqrt%2810a%29+%2B+3sqrt%28250a%5E3%29 Factor the second radicand:
sqrt%2810a%29+%2B+3sqrt%2825%2A10%2Aa%2Aa%5E2%29 Take the square root of 25 and of a%5E2 and move outside of the radical.
sqrt%2810a%29+%2B+3%2A5%2Aa%2Asqrt%2810a%29 Simplify.
sqrt%2810a%29+%2B+15a%2Asqrt%2810a%29 Factor the sqrt%2810a%29
