Answer:
Hello .I think the last one is the answer.
Step-by-step explanation:
because -6 is out of paranthes so we can multiple -6 with 3 and for so:
[tex] ( \frac{ {1.4}^{3} }{ {1.2}^{4} } ) ^{ - 6} = ( \frac{ {1.4}^{ - 18} }{ {1.2}^{ - 24} } )[/tex]
then you can up side down it so the minus will go away so:
[tex]( \frac{ {1.2}^{24} }{ {1.4}^{18} } )[/tex]
hope you understand
