Question

Calculati:b) 2⁴ × (-2³) : ((-2)¹⁵ : (-2)¹⁰)​

Answer 1

Răspuns:

4

Explicație pas cu pas:

${2}^{4} \times (- {2}^{3}) \div ((- {2})^{15} \div (- {2})^{10}) =$

$= - {2}^{4} \times {2}^{3} \div ( - {2}^{15} \div {2}^{10})$

$= - {2}^{4 + 3} \div( - {2}^{15 - 10})$

$= - {2}^{7} \div( - {2}^{5})$

$= {2}^{7} \div{2}^{5}$

$= {2}^{7 - 5}$

$= {2}^{2} = 4$
