Question

Помогите пожалуйста :)

Answer 1

$4) \\ 7 {}^{ - 7} \times( \frac{8}{7} ) {}^{ - 3} = \frac{1}{7 {}^{7} } \times \frac{7 {}^{3} }{8 {}^{3} } = \frac{1}{7 {}^{4} \times {8}^{3} }$

$5) \\ (\frac{1}{16} ) {}^{ - 3} \div ( \frac{4}{2} ) {}^{3} = 16 {}^{3} \times \frac{4 {}^{3} }{2 {}^{3} } = 16 {}^{3} \times \frac{1}{8} = 16 {}^{2} \times 2$

$6) \\ (\frac{7}{8} ) {}^{3} \times (2 \times 7) {}^{ - 2} = \frac{7 {}^{3} }{ {8}^{3} } \times \frac{1}{(2 \times7 ) {}^{2} } = \frac{7}{2 {}^{6} \times 2 {}^{2} } = \frac{7}{2 {}^{8} }$

$7) \frac{2 {}^{6} \times {16}^{ - 4} }{ {2}^{3} } = \frac{2 { }^{3} }{16 {}^{4} } = \frac{1}{16 {}^{3} \times 2 }$

Answer 2

Ответ:

Объяснение:

4). 7^(-7)*(8/7)^(-3)=1/7^7 *(7/8)^3=1/(7^4 *8^3)=1/(2401*512)=1/1229312

5). (1/16)^(-3):(4/2)^3=4^6 *8/4^3=4^3 *8=64*8=512

6). (7/8)^3 *(2*7)^(-2)=(7^3)/8^3 *1/(4*7^2)=7/(512*4)=7/2048

7). 2^6 *16^(-4)/2^3=(2^3)/16^4=(2^3)/(8^4 *2)=1/(4096*2)=1/8192
