Question

b) x=2 la puterea 11- 2 la puterea 10
Va rog ajutați-mă ​

Answer 1

$\bf x ={2}^{11} - {2}^{10}$

$\bf x ={2}^{10} \cdot\big( {2}^{11 - 10} - {2}^{10 - 10} \big)$

$\bf x ={2}^{10} \cdot\big( {2}^{1} - {2}^{0} \big)$

$\bf x ={2}^{10} \cdot\big( {2}-1 \big)$

$\bf x ={2}^{10} \cdot1$

$\red{ \boxed{\bf x ={2}^{10}}}$

Answer 2

$\it x=2^{11}-2^{10}=2^{10}(2-1)=2^{10}$
