Simplify the exponents first so [5(4)+ 4(3)]/ [4(8-4)]. Then simplify by multiplying 5×4 and 4×3 so (20+12) is in the numerator. Then add and subtract what's in the parentheses so it would be 32/(4×4). Then multiply 4×4 so it's 32/16 which equals 2. Just go through the order of operations GEMDAS to solve those problems.
