Question

log base( -1/3) power 81​

Answer 1

= -1/3^81

We can do this easily by reciprocal,

So, =3/1^81

= Let log-1/3^81 = x

⇒ 81 = (-1/3)x

⇒ 34 = (-1/3)x = 3-x

∴ x = -4

Hope this'll help you.

Answer 2

Step-by-step explanation:

The 81 is the power, and so it is placed after the “log”. Thus we have: 34 = 81 is the same as log381 = 4. To read this expression, we say “the logarithm base 3 of 81 equals 4.” This is equivalent to saying “ 3 to the 4th power equals 81.”
