(8la puterea x)la putere2÷16la puterea3 egal 64

​

Answer 1

$( {8}^{x} )^{2} \div {16}^{3} = 64$

${8}^{2x} \div {16}^{3} = 64$

${8}^{2x} \div {2}^{12} = 64$

${8}^{2x} \div {2}^{12} = {2}^{6}$

${2}^{6x} \div {2}^{12} = {2}^{6}$

${2}^{6x - 12} = {2}^{6}$

$6x - 12 = 6$

$6x = 6 + 12$

$6x = 18$

$x = 3$
