Question

${3}^{3} \times (243) ^{ \frac{ - 2}{3} } \times 9 {}^{ \frac{ - 1}{3} }$
Evaluate(step by step)​

Answer 1

Step-by-step explanation:

$(3) {}^{3} \times (3) {}^{5 \times - 2 \div 3} \times (3) {}^{2 \times - 1 \div 3} \\ \\ 3 {}^{3} \times 3 {}^{ - 10 \div 3} \times 3 {}^{ - 2 \div 3} \\ \\ 3 {}^{(3 + ( - 10 \div 3) - (2 \div 3))} \\ \\ 3 {}^{( - 1 \div 3) - (2 \div 3)} \\ \\ 3 {}^{ - 1} \\ \\ = 1 \div 3$
