Question

Find the value of: (i) [(4-1 - 5-1)-1 ] ÷ [ (52)3 x 5-5] (ii) [(1/4)-1 + (1/3)-2 - (1/2)-3 ] ÷ 52 STEPS NEEDED

Answer 1

Answer:

$(i)(((4 - 1) - (5 - 1)) - 1) \div ((52)3 \times 5 - 5 \\ (((3) - (4)) - 1) \div (780) \times 0 \\ ( - 2) \div 0 \\ 0 \: ans \\ \\ \\ \\ 2)(( \frac{1}{4} ) - 1 +( \frac{1}{3} ) - 2 - ( \frac{1}{2} ) - 3) \div 52 \\ = ( \frac{1 - 4}{4} ) + ( \frac{1 - 6}{3} ) - ( \frac{1 - 6}{2} ) \div 52 \\ = ( \frac{ - 3}{4} ) + ( \frac{ - 5}{3} ) - ( \frac{ - 5}{2} ) \div 52 \\ = \frac{( - 9) + ( - 20) - ( - 30)}{12} \div 52 \\ = \frac{1}{12} \div 52 \\ = \frac{1}{12} \times \frac{1}{52} \\ = \frac{1}{624}$
