Find the least common denominator. 3/18x^5 , 5/36x^2 , 8/9x^3

Your least common denominator is 36. 

So 3/18x⁵ becomes 6/36x⁵

5/36x² stays

8/9x³ becomes 32/36x³

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
