    \[\left( 3\sqrt{10+4} \right)\left( 4\sqrt{10-5} \right)\] simplify in radical expression.

    3*4=12 10+4=14 10-5=5 14(5)=70 \[12\sqrt{70}\]

    you can if you want, but the above cannot be simplfied anymore since 70=2*5*7 there are no perfect squares in 70

    so this is multiplication right? not addition or subtraction or division? it is definitely multplication, right?

    if it does, we can try to follow the logic of the problem they did and see if we can get the answer they are looking for even though it will not be correct

    sqrt(5)sqrt(2)+sqrt(5)*3+sqrt(5)sqrt(2)+sqrt(2)3 =sqrt(10)+3sqrt(5)+sqrt(10)+2sqrt(2) =2sqrt(10)+3sqrt(5)+2sqrt(2)

    On that practice question, I don't get how they got 24 +(sqrt)6

  38. myininaya

    ok lets pretend the problem was 3(sqrt(10)+4)2(sqrt(10)-5) 6(sqrt(10)+4)(sqrt(10)-5) 6(10-5sqrt(10)+4sqrt(10)-20) 60-sqrt(10)-20 40-sqrt(10 so this doesn't work
