Question

(2+√3+1/2+√3)³please solve my doubt sir​

Answer 1

Answer:

Given ( 2+√3+1/2+√3 )^3

now

add all the possible terms inside the bracket, We get:-

(5/2+2√3)^3

using identity ( a+b )^3 = a^3+ b^3+3ab(a+b)

(5/2+2√3)^3 = (5/2)^3+(2√3)^3+3(5/2)(2√3){5/2+2√3}

= 125/8+24√3+15√3{(5+4√3)/2}

=125/8+24√3+(75√3+180)/2

= (125+192√3+300√3+720)/8

=(845+492√3)/8
