BODMAS rule is an acronym used to remember the order of operations to be followed while solving expressions in mathematics. First, we solve brackets, then powers or roots, then division or multiplication (whatever comes first from the left side of the expression), and then at last subtraction or addition.




Applying BODMAS rule:


"((25\u00f77\u00d712)\u00f75\u00d728)\u00f73\\\\\n\\implies((3.5714285714285716\u00d712)\u00f75\u00d728)\u00f73\\\\\n\\implies(42.85714285714286\u00f75\u00d728)\u00f73\\\\\n\\implies(8.571428571428573\u00d728)\u00f73\\\\\n\\implies240.00000000000006\u00f73\\\\\n\\implies80.00000000000001\\approx 80"
