Question 887208: What is radical50 plus radical 10? Please show steps :-)

i believe you mean simplify the expression.
start with sqrt(50) + sqrt(10)
since 10 = 2 * 5 and 50 = 5 * 10 = 5 * 2 * 5, your expression becomes:
sqrt(5 * 2 * 5) + sqrt(2 * 5) which becomes:
sqrt(5^2 * 2) + sqrt(2 * 5) which becomes:
sqrt(5^2) * sqrt(2) + sqrt(2) * sqrt(5) which becomes:
5 * sqrt(2) + sqrt(2) * sqrt(5).
factor out the common term of sqrt(2) and you get:
sqrt(2) * (5 + sqrt(5)
confirm by evaluating sqrt(50) + sqrt(10) and comparing it to the evaluation of sqrt(2) * (5 + sqrt(5)) to see if you get the same answer from both.
sqrt(50) + sqrt(10) = 10.23334547
sqrt(2) * (5 + sqrt(5)) = 10.23334547
they're the same so the simplification problem is successful.
