Write 4 radical expressions that are each equivalent to 8 times the square root of x . One expression must use addition, one must use subtraction, one must use multiplication, and one must use division.

Here is the first one: \(\displaystyle \sqrt{25x}+\sqrt{9x}=8\sqrt{x}\). (i.e. 5+3=8)

Now, you do the others.
