Question

Am nevoie urgent! dau puncte și coroana! ​

Answer 1

Explicație pas cu pas:

$36 = {6}^{2}$

$64 = {2}^{6} = {( {2}^{3} )}^{2} = {8}^{2}$

$1 = {1}^{2}$

$169 = {13}^{2}$

$324 = {2}^{2} \cdot {3}^{4} = {(2 \cdot {3}^{2} )}^{2} = {18}^{2}$

${2}^{8} \cdot 81 = {2}^{8} \cdot {3}^{4} = {( {2}^{4} \cdot {3}^{2} )}^{2} = {144}^{2}$

$49 \cdot 64 \cdot {5}^{2} = {7}^{2} \cdot {2}^{6} \cdot {5}^{2} = {(7 \cdot {2}^{3} \cdot 5 )}^{2} = {280}^{2}$

${4}^{3} \cdot {5}^{6} = {( {2}^{2} )}^{3} \cdot {5}^{6} = {2}^{6} \cdot {5}^{6} = {({2}^{3} \cdot {5}^{3} )}^{2} = {1000}^{2}$

${16}^{3} \cdot {( - 5)}^{4} = {( {2}^{4} )}^{3} \cdot {5}^{4} = {2}^{12} \cdot {5}^{4} = {({2}^{6} \cdot {5}^{2} )}^{2} = {1600}^{2}$

$121 \cdot 169 = {11}^{2} \cdot {13}^{2} = {(11 \cdot 13)}^{2} = {143}^{2}$
