Answer 1

Ответ:

$2 {}^{12} \times 2 {}^{ - 9} = 2 {}^{12 - 9} = 2 {}^{3} = 2 \times 2 \times 2 = 4 \times 2 = \boxed{8}$

$c {}^{13} \div c {}^{7} = c {}^{13 - 7} = \boxed{c {}^{6} }$

$(x {}^{4} ) {}^{6} = x {}^{4 \times 6} = \boxed{x {}^{24} }$

$(a b) {}^{4} = \boxed{a {}^{4} b {}^{4} }$

$( \frac{y}{2} ) {}^{4} = \frac{y {}^{4} }{2 {}^{4} } = \boxed{ \frac{y {}^{4} }{16} }$
