If you then want to go on to factor it, your answer would be
The answer is unreasonable because the value of x is between 2 and 3.The error is : she did not introducing logs in solving the equation.
Step-by-step explanation:
The question is
Here answers is unreasonable because, she can test with powers of seven like;
7²=49
7³=343
So this means the value of x lies between 2 and 3, so here answer 11.71 is unreasonable
b) In this case, to solve the equation, introduce logs both sides
