If A= 7 25 and 3 2 < A < 2 , then A 4 + A 2 - 2 A=

Options

  1. A1 10 + 27 625
  2. B3 10 - 27 625
  3. C3 10 + 27 625
  4. D1 10 - 27 625

Correct answer

A. 1 10 + 27 625

Step-by-step solution

Given, A= 7 25 and 3 2 < A < 2 Then, 2 A=2 ( 49 625 )-1= 98-625 625 =- 527 625 A 2 =- 4 5 and A 4 = 1 10 So, A 4 + A 2 - 2 A= 1 10 + 27 625 .
