Đáp án:
1) \({x^8}\)
Giải thích các bước giải:
\(\begin{array}{l}
1){\left( {{x^4}} \right)^2} = {x^{4.2}} = {x^8}\\
10){\left( {{x^5}} \right)^6} = {x^{5.6}} = {x^{30}}\\
13){\left( {\dfrac{1}{{{2^3}}}} \right)^4} = \dfrac{1}{{{2^{3.4}}}} = \dfrac{1}{{{2^{12}}}}\\
29){\left( {\dfrac{{{{\left( { - 3} \right)}^3}}}{{{2^3}}}} \right)^{ - x}}\\
= {\left( {\dfrac{{{2^3}}}{{ - {3^3}}}} \right)^x} = \dfrac{{{2^{3x}}}}{{ - {3^{3x}}}}\\
30){\left( {\dfrac{{{2^2}}}{{{3^2}}}} \right)^{ - x}} = {\left( {\dfrac{4}{9}} \right)^{ - x}} = {\left( {\dfrac{9}{4}} \right)^x} = \dfrac{{{9^x}}}{{{4^x}}}
\end{array}\)
