$- 7 )^{ - 2} \times 3^{ - 1} \times 11 ^{ - 2} \times a^{ - 4} \div 22 ^{ - 4} \times 21 ^{ - 3} \times a ^{ - 6}$
solve it pls​

Answer 1

Answer:

7 )^{ - 2} \times 3^{ - 1} \times 11 ^{ - 2} \times a^{ - 4} \div 22 ^{ - 4} \times 21 ^{ - 3} \times a ^{ - 6} 

- 7 )^{ - 2} \times 3^{ - 1} \times 11 ^{ - 2} \times a^{ - 4} \div 22 ^{ - 4} \times 21 ^{ - 3} \times a ^{ - 6}−7)−2×3−1×11−2×a−4÷22−4×21−3×a−6
