me ajudem pfvr

Answer 1

Resposta:

Eis as respostas para os cálculos das potências dadas:

• b) (+3)² = 9;
• c) (+5)² = 25;
• d) (-5)³ = -125;
• e) (+2)³ = 8;
• f) (+4)³ = 64;
• g) (-2)⁴ = 16.
• Explicação passo a passo:

Vamos calcular os valores pedidos:

• b) (+3)² = (+3)·(+3) = (+9) = 9;
• c) (+5)² = (+5)·(+5) = (=25) = 25;
• d) (-5)³ = (-5)·(-5)·(-5) = (+25)·(-5) = -125;
• e) (+2)³ = (+2)·(+2)·(+2) = (+4)·(+2) = (+8) = 8;
• f) (+4)³ = (+4)·(+4)·(+4) = (+16)·(+4) = (+64) = 64;
• g) (-2)⁴ = (-2)·(-2)·(-2)·(-2) = (+4)·(+4) = (+16) = 16.
