The first step to figuring this question out is to simplify the expression by multiplying the exponents.
[tex] b^{4x3} [/tex]
When you multiply these exponents together,, you should get the following:
[tex] b^{12} [/tex] = [tex] b^{12} [/tex]
Now take the root of both sides of the equation to get your final expression.
b = b
This means that this statement is true for any value of b because both sides of the equation are identical.
