Question

If a=1/7+4root3 b=1/7-4root3 find the value of( a )square +(b) square​

Answer 1

Answer:

96.04

Step-by-step explanation:

a^ + b ^2 = ( a + b ) ^ 2 - 2ab

               =

(1/7+ 4√3 + 1/7 - 4√3 )^ 2 - 2 ( 1/7+ 4√3) ( 1/7 - 4√3)

= 1/49- 2 ( 1/49 - 48  )

=    1 - ( 2 - 49* 48 * 2) / 49

= 1 + 4702 / 49

= 96.04
