Can you add or subtract under the radical?
No, you cannot add or subtract under the radical. The radical represents the square root function, and it only operates on the number or expression that is inside the radical. To add or subtract, you need to simplify the expressions inside the radical first.
What does 3 radical 2 plus 4 radical 2 equal?
first the two numbers have the same radicand which is radical 2 so we just add the numbers before them to become 7 radical 2
How do you express radicals in simlpest form?
by doing the operation that the radical tells you to do If its a square, like sqrt(36), the simplest form is 6. if its something like 48, it can be simplified. what i did at first to help me with radicals is this: I set parenthese up with a square on the outside. ( )^2 I ask myself what is the number in there that when squared, is divisible by the original number. So in the case of 48 i would write (4)^2*3. because 4 squared is 16, and 16x3 is 48. What ever in the parenthese goes on the out side of the radical what ever is left over goes under the radical. so the answer to sqrt(48) is 4sqrt(3) You want to work with the highest possible number that your squaring, to get the simplest form of the radical. I could have said 2sqrt(12), that is also 48, but 12 can be simplified further.
How do you simplify radical 3 over 4 minus radical 4 over 3?
Start by finding a common denominator. If the radical includes the entire fraction (3/4 for the first part), the common denominator would be square root of 12.
How would you simplify a problem like 3 radical 16?
Let's assume that \/" is the radical sign.3\/"16The first thing to do would be to solve for the part under the radical.\/"16 = 4Then substitute that into the original problem.3\/"163*412 is the final answer.
