What is the smallest number by which you have to multiply the product 3 x 4 x 5 x 11 x 15 to get a perfect square number? *

  11

Step-by-step explanation:

The prime factorization of the given product is ...

  3 × 2^2 × 5 × 11 × 3·5 = 2^2 × 3^2 × 5^2 × 11

The factor required for this to be a perfect square is 11.

Check

3·4·5·11·15 = 9900 ≈ 99.499^2

9900·11 = 108,900 = 330^2 . . . a perfect square number

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

40 is the final : )
