If a + b + c + d = 4 then find the value of 1/(1-a)(1-b)(1-c) + 1/(1-b)(1-c)(1-d) + 1/(1-c)(1-d)(1-a) + 1/(1-d)(1-b)(1-a). |

Answer» If a + b + c + d = 4, the value of 1/(1-a)(1-b)(1-c) + 1/(1-b)(1-c)(1-d) + 1/(1-c)(1-d)(1-a) + 1/(1-d)(1-b)(1-a) is 0 We need to reduce the given expression and then add the value of (a + b + c + d) |
