Which of the following statement is true?

The correct option is 1.

Step-by-step explanation:

If a number is defined as , where p and q are distinct integers and q≠0, then it is called a rational number.

For example: 0.2, 3/4, 5%.

If a number can not be defined as , where p and q are integers and q≠0, then it is called an irrational number.

For example: √2, √3, √(0.3).

The given numbers can be written as

Since is the product of two irrational numbers , therefore is an irrational number.

If any numbers is divisible by an irrational number, then the resultant number is irrational. So, is an irrational number.

Both and are irrational. Therefore the correct option is 1.

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
