Question

log subscript A space B, where B equals fraction numerator 12 over denominator 3 plus square root of 5 plus square root of 8 end fraction and A equals square root of 1 plus square root of 2 plus square root of 5 minus square root of 10 is

  1. a negative integer
  2. a prime integer
  3. a positive integer
  4. an even–natural

hintHint:

In this question, we have to find the. Where the value of A and B is given A = √1 + √2 + √5- √10And B=fraction numerator 12 over denominator 3 plus square root of 5 plus square root of 8 end fraction. To solve this question, solve B, rationalize it find the value B then find the log subscript a B.

The correct answer is: a positive integer
