Question

CALCULE 8²= (-13)² (-7)³ (-3)4 (-0,9)¹

Answer 1

${8}^{2} = ( - 13)( - 7) {}^{3} ( - 3)4 ( - 0.9) ^{1}$

$log_{8} (8 ^{2} ) = log_{8}(( - {13})^{2} \times {7}^{3} \times 4 \times ( - 0.9)^{1} )$

$2 = log_{8}(( - 13) ^{2} \times {7}^{3} \times 4 \times ( - 0.9) ^{1} )$

$log_{8}(( - 13) ^{2} \times {7}^{3} \times 4 \times ( - 0.9) ^{1} ) = 2$
