Answer 1

$1)x^{2}\cdot x^{10}=x^{2+10} =\boxed{x^{12}} \\\\2)x^{11}:x^{8}=x^{11-8}=\boxed{x^{3}}\\\\3)(x^{3} )^{5}=x^{3\cdot 5} =\boxed{x^{15}} \\\\4)(ac^{2})^{3}=a^{3}\cdot(c^{2})^{3}=\boxed{a^{3}c^{6}}$

Answer 2

$a) \: x {}^{2} \times {x}^{10} = {x}^{2 + 10} = {x}^{12}\\ b) {x}^{11} \div x {}^{8} = x {}^{11 - 8} = {x}^{3} \\ c)( {x}^{3} ) {}^{5} = x {}^{3 \times 5} = {x}^{15} \\ d)( a{c}^{2} ) {}^{3} = a {}^{2} c {}^{6}$
