ABSTRACT
In this paper, we obtain some properties of the Zadeh extension (is restricted to fuzzy number space E, and denoted by log a ˜ u https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429076893/758c34ac-b572-4988-b7a6-5484e7610c53/content/eq209.tif"/> ) of function g(x) = log a x about continuity, monotonicity, convexity (or concavity), differentiability and integration.
