Which of the following is an irrational number?
tamaranim1 [39]

Answer:

The correct option is;

0.100100010000...

Step-by-step explanation:

An irrational number in mathematics are the subset of real numbers that are not rational numbers such as √2, π, e. As such it is not possible to express an irrational number as a ratio of two integers, or expressed in the form of a simple fraction.

The decimal portion of the expression of an irrational number are non periodic and they do not terminate. Transcendental, which are non algebraic, numbers are all irrational numbers

In the question, the number 0.100100010000... has non terminating non recurring decimals and is therefore an irrational number.

Please tell me correct and​
choli [55]

Answer:

\frac{1}{4} or 0.25 (they're the same)

Step-by-step explanation:

First Part:

  1. 4^{3} = 64  
  2. 8^{2} = 64  
  3. 2 = 2  
  4. Multiply them together: 64 × 64 × 2 = 8192

Second Part:

  1. 2^{7} = 128  
  2. 16^{2} = 256  
  3. Multiply them together: 128 × 256 = 32768

Wrap it all up:

  1. 8192 ÷ 32768 = 0.25 = 1/4

I hope this helps!
