Question

the L.C.M of 6,12 and n is 660 . find all the possible values of n

Answer 1

Answer:

First of all find out the factors of 660 itself.

660 = 2² × 3 × 5 × 11

We know, the factors of 6 are 2 × 3 & 12 are 2² × 3.

So, definitely, (5 × 11) belongs to n.

Therefore, trying to formulate the indices of 2 and 3 to compute the range we get,

n can be any of the below:

1. 2^{0}2

0

× 3^{0}3

0

× 5 × 11.

2. 2^{0}2

0

× 3 × 5 × 11.

3. 2 × 3^{0}3

0

× 5 × 11.

4. 2 × 3 × 5 × 11.

5. 2² × 3^{0}3

0

× 5 × 11.

6. 2² × 3 × 5 × 11.

The combination we got is from 2 * 3 = 6.

Answer 2

Step-by-step explanation:

Polyester is a man-made or synthetic fibre made up of repeating units of a chemical substance called esters. Esters are sweet smelling compounds, which are primarily made of carbon, hydrogen, and oxygen. Being crisp and easy to wash, polyester is perfect for making clothes
