Answer 2

Răspuns:

$9.\ \frac{-4}{5}$

$10.\ x=14$

Explicație pas cu pas:

$9.\ [(-\frac{3}{5})^9]^4:(-\frac{3}{5})^{34}-\frac{25+4}{25}=(-\frac{3}{5})^{36}:(-\frac{3}{5})^{34}-\frac{29}{25}\\\\(-\frac{3}{5})^{36-34} -\frac{29}{25}=(-\frac{3}{5})^{2} -\frac{29}{25}=\frac{9}{25}-\frac{29}{25}=\frac{9-29}{25}=\frac{-20}{25}=\frac{-4}{5}$

$10.$

$4^x*2^5=8^{11}\\\\(2^2)^x*2^5=(2^3)^{11}\\\\2^{2x}*2^5=2^{33}\\\\2^{2x+5}=2^{33}\\\\2x+5=33\\\\2x=33-5\\\\2x=28\\\\x=14$
