Question 73435: I need help. I tried to solve the following radical expression but think it;s wrong... 2 square root of 18 times 7 square root of 6. The answer I ended up with was 84 square root of 3. Is this right? Also, is there a shorter way to write square root in computer language? Thank you.

You can put this solution on YOUR website!
+2sqrt%2818%29+%2A+7sqrt%286%29+
Since you are multiplying ... Multiply the co-efficients and the roots separately
+2%2A7+%2A+sqrt%2818+%2A6%29+
+14+%2A+sqrt%283%2A6%2A6%29+
Pull out the 6
+14+%2A+6+%2A+sqrt%283%29+
Multiply
+84sqrt%283%29+

No clue on the computer Language question.
Sorry
