Prove that no integer in the following sequence is a perfect square:
11, 111, 1111, 11111, ...

 

Answer:

It starts from 11

So 1 is not included

Try other numbers:

121 is not the same with 111

Difference B/W Mixture And Compound?

Difference b/w mixture and compound?   Good Day.... Compound - is a combination of two or more elements which are chemically bonded either by ionic bond or covalent bond. The atoms or elements composing the compound have a fixed proportion. The elements or atoms cannot be separated by physical means. example of compound: water (H2O)  composed of 2 hydrogen and 1 oxygen. Cannot be separated by filtration or evaporation. Mixture -  a combination of two or more substances or compound that are not chemically joined or bonded. Mixture doesnt have a fixed proportion of the substance being mixed. The substances can be separated by physical means. Example of mixture : water (H2O) with sand. You can separate water from sand by filtration and evaporation which is a physical means of separating mixtures. Hope it helps...=)
