Question

Simplifique

A) ( 7 elevado a 2) ^3
( 7 elevado a 3) ^2


B) ( 3. 5 elevado a 2) ^3
( 3 elevado a 2. 5) ^2

Answer 1

Nesses casos somente somamos os expoentes

A) I - ({7}^{2})^{3} = {7}^{2} + {7}^{2} + {7}^{2} = {7}^{2+2+2} = {7}^{6}
II - ({7}^{3})^{2} = {7}^{9}

B) I - ({3.5}^{2})^{3} = {3.5}^{5}
II - ({3}^{2.5})^{2} = {3}^{4.5}
