Explanation Given: The expression is e 3 x − 4 = 20 . Formula used: For any positive real number M , any real number a , and any positive base c ≠ 1 , the power formula of logarithm is, log c ( M ) a = a log c M . Calculation: Consider the expression: e 3 x − 4 = 20 . Take log on both sides. log e e 3 x − 4 = log e 20 Use the power property, log b ( M a ) = a log b M to solve the expression

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
