Question

.If A is equal to √5+1+ √5-1 B is equal to √5- 1+ √5 + 1 then A+B is

Answer 1

Answer:

A + B = 4√5

Step-by-step explanation:

We have,

A = √5 + 1 + √5 - 1

B = √5 - 1 + √5 + 1

Then,

A + B = (√5 + 1 + √5 - 1) + (√5 - 1 + √5 + 1)

A + B = √5 + 1 + √5 - 1 + √5 - 1 + √5 + 1

A + B = √5 + √5 + √5 + √5 + 1 - 1 + 1 - 1

A + B = 4√5 + 0

Hence,

A + B = 4√5
