Question

Помогите пожалуйста ​

Answer 1

Объяснение:

а)

${y}^{12} \div ( {y}^{6} )^{2} = {y}^{12 - 6 \times 2} = {y}^{0} = 1$

б)

$( {y}^{4})^{5} \div ( {y}^{4} )^{2} = {y}^{4 \times 5 - 4 \times 2} = {y}^{12}$

в)

$(y \times {y}^{2})^{3} \div (y \times {y}^{3} )^{2} = {y}^{(1 + 2) \times 3 - (1 + 3) \times 2} = {y}^{1} = y$
