Question

4log64 + 4log16 - 4log256

Answer 1

4log64 + 4log16 - 4log256

= 4 log 4^3 + 4 log 4^2 - 4 log 4^4

=3 . 4log 4 + 2. 4 log 4 - 4. 4log 4

= 3 + 2 - 4

=1

Answer 2

⁴log64 + ⁴log16 - ⁴log256

= ⁴ log (64 x 16) / 256

= ⁴ log 1.024/256

= ⁴ log 4

= 1

Atau cara lain

⁴ log 64 + ⁴ log 16 - ⁴ log 256

= ⁴ log 4³ + ⁴ log 4² - ⁴ log 4⁴

= 3. ⁴ log 4 + 2. ⁴ log 4 - 4. ⁴ log 4

= 3.1 + 2.1 - 4.1

= 3 + 2 - 4

= 1
