Question

4. Выполните действия: a) x³ . x5 . x q¹8 b) : a10 c) (2x^) d) (-3x²y)​

Answer 1

${x}^{3} \times {x}^{5} \times x = {x}^{3 + 5 + 1} = {x}^{9}$

$\frac{a {}^{18} }{ {a}^{10} } = {a}^{18 - 10} = {a}^{8}$

$(2 {x}^{3} ) {}^{3} = {2}^{3} \times {x}^{3 \times 3} = 8 {x}^{9}$

$( - 3 {x}^{2} y) {}^{3} = ( - 3) { }^{3} \times x {}^{2 \times 3} y {}^{3} = - 27x {}^{6} y {}^{3}$
