12 and 8 -- Least Common Multiple is 24. 24 = 12*2, 24 = 8*3

(5/12)*(2/2) = 10/24

(-3/8)*(3/3) = -9/24

10/24 + (-9/29) = 10/24 - 9/24 = (10-9)/24 = 1/24

I need some assistance to varify my work

1) square route 2x(square route 10-square route x)?

2) (3 SQUARE ROUTE X+1)..PARENTHESE IS TO THE 2ND POWER?

3) square route 3xy (y to the 3rd power) * square route 18xy (y is to the second power)?

4) 3 square route of 20x-2 square route of 45x+square route of 80x?

5) -4x square route xy- x square route xy?


If someone could help I would appreciate it, thanks [/list][/code][/b]

P.S. When you post your question, please note that the word is spelled "root" ("route" is something you drive on). Also, please use grouping symbols or some other formatting to clarify your meaning. For instance, does "square route 3xy (y to the 3rd power)" mean "sqrt(3)xyy³" or "sqrt(3x)yy³" or "sqrt(3xy³)" or something else? Also, please include the instructions, so the tutors can tell what you are supposed to be doing. Also, please show the steps you have tried thus far. Thank you.
