Numbers

Three. The prime numbers (factors) of 60 are: 2,3,5

11

1 + 1 = 2

Example: 30 and 42

Factor them.

2 x 3 x 5 = 30

2 x 3 x 7 = 42

Combine the factors, eliminating duplicates.

2 x 3 x 5 x 7 = 210, the LCM

Sometimes. The square root of 2 is, but the square root of 9 is not.

the set of factors

A prime number is a positive integer that has only two factors: one and itself.

Some mathematicians consider 0 as part of the natural numbers. The set is denoted by Z, or Z0.

If you mean the greatest prime factor of 210 it is 7.

1

1 has one factor

Anyone who is doing math above 8th grade has to use integers, or at least know how to use them! Unless in special classes than they are learning at a lower level!

the exponent

Yes.

No, it is a composite number. Its factors are 1, 241, 3361 & 810001.

Sure. It's the ratio of -45 to 100.

Any number that you can write completely using only

digits and a decimal point is a rational number.

-5

(10100)100 .

square no. Means reapeating the particular no. Twice. For ex. 1* 1equal 1, 4 * 4 equal 16, 7 * 7 equal 49. The no.s 1, 4, 49 are sq. Nos . 2 * 3 equals 6 and 5 * 2 equalls 10 are not a square no. Two identical no are multiplied and tie resultent is called a square no. Any two identical nos are multiplied does not give 14. So...

3*3 = 9 and 4*4=16. There are no integers between 3 and 4 so there are no square numbers between 9 and 16.

61, 67, 71, 73 and 79.

It is the only even prime number.

There are none as 5189 is a prime number.

There is no more the dielectric constant for insulators than the colour for shirts.

Every shirt has a colour, and every insulator has a dielectric constant.

Find out what material your insulator is, then look in Kaye & Labey or any good handbook for radio and electronics engineers.

644 is composite. All whole numbers ending in four are composite.
