okay one sec

anonymous · Answer

try now

bibby · Answer

recall this property of radicals. Basically the stuff inside is like an x or y and the number outside is the coefficient.

For example:
$$5\sqrt{34}+2\sqrt{34}-4\sqrt{34}=3\sqrt{34}$$

okay, i know that its just im having trouble trying to solve it

bibby · Answer

k, then rewrite the statement.$$\large 5\sqrt7 + 12\sqrt6 - 10\sqrt7 - 5\sqrt6=5\sqrt7 - 10\sqrt7 + 12\sqrt6  - 5\sqrt6$$

anonymous · Answer

okay, then ...don't you have to change it into a rational exponent

bibby · Answer

Not for this. Here, we just combine the like terms. It's exactly the same as the example above.

the sqrt7's are like x, the sqrt6 are like y.

You just combine the x and ys
