1. Answer:

   Answer is

   4(1/2) – 4(0) ×{5(√3) – 6(√3)}

   = 4/2 -0(5(√3) – 6(√3)) … from (2)

   = 2

   I have done it by DMAS i.e first division then multiple then Addition and subtraction

   This is the right way according to me.

   Another way from(2)

   = 4/2 -(-1√3)

   =4/2 + 1√3

   =4/2 +2√3/2

   = (4+ 2√3)/2

   This can be the answer if you cancel 0 first

   but in my opinion it is wrong and first answer is correct

   What is correct answer comment me after watching??
