Question

1.53. Упростите выражение х^12 : (2х^3 •х^4 – х^2•x^5);​

Answer 1

Ответ:

$x {}^{12} \div (2x {}^{3} \times x {}^{4} - x {}^{2} \times x {}^{5} ) = x {}^{12} \div ((2 - 1)x {}^{3} \times x {}^{2} \times x {}^{2} ) = x {}^{12} \div (1x {}^{3} \times x {}^{2} \times x {}^{2} = x {}^{12} \div x {}^{7} = x {}^{5}$

Answer 2

Ответ:

${x}^{12} \div ( {2x}^{3} \times {x}^{4} - {x}^{2} \times {x}^{5} ) = {x}^{12} ((1 - 2) {x}^{3} \times {x}^{2} \times {x}^{2}) = {x}^{12} ( {x}^{3} \times {x}^{2} \times {x}^{2} ) = {x}^{12} \div {x}^{7} = {x}^{5}$
