Question

 valor de (log₂ 64 + log₃ 9 – log₅ 25 ) . log₄ 4 é: 

2

3

4

5

6​

Answer 1

Explicação passo-a-passo:

• log₂ 64 = log₂ 2⁶ = 6

• log₃ 9 = log₃ 3² = 2

• log₅ 25 = log₅ 5² = 2

• log₄ 4 = log₄ 4¹ = 1

Logo:

(log₂ 64 + log₃ 9 – log₅ 25) . log₄ 4

= (6 + 2 - 2) . 1

= (8 - 2) . 1

= 6 . 1

= 6

Answer 2

Resposta:

log ² 64-log ³ 27 =

log ² 2⁶ - log ³ 3 ³ =

(6.log ² 2) - (3.log 3) =

(6.1) - (3.1) =

6-3 =

3
