Question

Пожалуйста помогите мне!!!

Answer 1

1)$(5^{3}*5^{2} )^{4}:5^{15}=(5^{3+2})^{4}:5^{15}=5^{5*4}:5^{15}=5^{20}:5^{15}=5^{20-15}=5^{5}=3125$

2) $(3^{3})^{4}*9^{2}:3^{10}=3^{3*4}*(3^{2})^{2}:3^{10}=3^{12}*3^{4}:3^{10}=3^{12+4-10}=3^{6}=729$

3)$3^{2}*(-3)^{4}-3^{6}=3^{2}*3^{4}-3^{6}=3^{2+4}-3^{6}=3^{6}-3^{6}=0$

4)$25^{3}:5^{2}=(5^{2})^{3}:5^{2}=5^{6}:5^{2}=5^{6-2}=5^{4}=625$

5) $3^{4}*9^{1}=3^{4}*3^{2}=3^{4+2}=3^{6}=729$

6)$4^{2}*(-4)^{1}=-4^{2}*4^{1}=-4^{3}=-64$
