Question

(2+√3)⁴+(2-√3)⁴=x+y√3 then y=?
​

Answer 1

Answer:

x+√3y=194

Step-by-step explanation:

(2+√3)⁴+(2-√3)⁴=x+y√3

expand using algebraic method

97+56√3+(2-√3)⁴=x+y√3

97+56√3+97-56√3=x+√3y

97+56√3=x+√3y

since two opposite add up to zero remove them from the expression

97+97=x+√3y

194=x+√3y

the swap the sides of the equation

x+√3y=194

thats how I got the answer

x+√3y=194
