(a)
To find: Whether the given value of x is a solution of the equation or not.
(a)
Answer to Problem 4E
The x -value
Explanation of Solution
Given information:
The equation
Formula used:
Substitute the provided value of the variable in the function to check whether left hand side of the equation is equal to right hand side of the equation.
Exponential and logarithm functions are reciprocal to each other and it is mathematically expressed as
Calculation:
Consider the provided equation
Substitute x as 1+ln 15 in the left hand side of the above equation,
Simplify it further as,
The above equation is true.
Therefore,
Hence, the x -value,
(b)
To find: Whether the given value of x is a solution of the equation or not.
(b)
Answer to Problem 4E
