Instructions: drag the tiles to the correct boxes to complete the pairs. match the pairs of rational expressions with their least common denominators.

1st Tile = 144m²n³

2nd tile =

3rd tile =

4th tile =

Step-by-step explanation:

In this question we have to find out the least common multiple of the denominators and pair them with the rational expressions.

LCM of 9m²n and 16mn²

prime factors of 9m²n = 3×3×m×m×n

prime factors of 16mn³ = 2×2×2×2×m×n×n×n

So LCM of both = 2×2×2×2×3×3×m×m×n×n×n = 144 m²n³

LCM of

prime factors of = 2×2×2×m×m×m×m×n×n

prime factors of = 2×3×3×m×m×n×n×n×n

LCM of both = 2×2×2×3×3×m×m×m×m×n×n×n×n =

Similarly LCM of will be

LCM of will be

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

not sure but it may be b, as i said i'm not sure.
