[tex](-2)^6:(2^4) =(-1*2)^6:2^4 = (-1)^6*2^6:2^4 = 2*6:2^4 = 2^(6-4)-2^2=4\\\\(3^2)^4=3^{4*2}=3^8=6561\\\\(5^3)^2=5^{2*3}=5^10=9765625\\\\(\frac{10}{5})^3 = 2^3 = 8\\\\(-8)^2=(-1*8)2=(-1)^2*8^2=8^2=(2^3)^2 = 2^{2*3} = 2^5 = 64\\\\(\frac{6}{7})^3 =\frac{6^3}{7^3}= \frac{(2*3)^3}{7^3}= \frac{2^3*3^3}{7^3}= \frac{8*27}{343} = \frac{216}{343}= 0,6297[/tex]
