Answer:


\frac{64}{49}


Step-by-step explanation:


As we can see the given expression as three complex parts and all are being multiplied.


Lets simplify each part separately and then multiply all of them in the end


Part1


(\frac{8.4.2}{8.7})^{2}  

Cancelling 8 in numerator with 8 in denominator


(\frac{4.2}{7})^{2}


(\frac{8}{7})^{2}


\frac{64}{49}


Part2


(\frac{8^{0} }{7^{-3} })^{3}


simpliying


(\frac{1}{7^{-3} })^{3}


({7^{3} })^{3}


7^{9}


Part3


Third part is 7^{-9}, and it does not need to be further simplified


Now multiplying all the three parts


\frac{64}{49}.7^{9}.7^{-9}


\frac{64}{49}.7^{9-9}


\frac{64}{49}.7^{0}


\frac{64}{49}.1


\frac{64}{49}


So our final answer is \frac{64}{49}
