Log27 81-log27 3 +4 Помогите!

Answer 1

Log₂₇81-log₂₇3+4=log₂₇(81/3)+4=log₂₇27+4=1+4=5.

Answer 2

To solve this expression, we can use the properties of logarithms. Specifically, we can use the fact that:

log_a (b) - log_a (c) = log_a (b/c)

Using this property, we can simplify the expression as follows:

log_27 (81) - log_27 (3) + 4

= log_27 (81/3) + 4 (using the above property)

= log_27 (27) + 4 (simplifying 81/3)

= 1 + 4 (since log_27 (27) = 1)

= 5

Therefore, the value of the expression is 5.
