Answer 1

$4.a) (2*7)^{14}=2^{14}*7^{14} \\ \\ b) (3*5)^{7} =3^{7}*5^{7} \\\\ e)=(3*8*5) ^{4} \\ \\ f)=(2*7)^{15} \\ \\ 5.a) (2*7)^{14}=2^{14}*7^{14} \\ \\ b) (3*5)^{7} =3^{7}*5^{7} \\ \\ e)=(3*8*5) ^{4} \\ \\ f)=(2*7)^{15} \\ \\ 6)a) (2)^{3})^{8}:(4)^{11}= \frac{2^{3*8} }{2^{2*11} } = \frac{ 2^{24} }{2^{22} } = 2^{2} =4$
$b)= \frac{3^{7*4}}{3^{2*13}} = \frac{3^{28}}{ 3^{26}} =3^{2}=9 \\ \\ e)5^{3*12}: 5^{2*17}=5x^{36}:5^{34}= 5^{2}=25 \\ \\ f)= 3^{4*36}: 3^{3*48}=3^{144}:3^{144}=1$
