How do I solve for x here? Use the properties of logarithms to find a value for x. Assume a,b, and M are constants.
Leona [35]

Yes, you're right! The first step is rewriting the equation as

\ln(a) + \ln(b^x) = M

Subtract \ln(a) from both sides:

\ln(b^x) = M-\ln(a)

Use the property \ln(a^b) = b\ln(a) to rewrite the equation as

x\ln(b) = M-\ln(a)

Divide both sides by \ln(b)

x = \dfrac{M-\ln(a)}{\ln(b)}

Alternative strategy:

Consider both sides as exponents of e:

e^{\ln(ab^x)} = e^M

Use e^{\ln(x)} = x to write

ab^x = e^M

Divide both sides by a:

b^x = \dfrac{e^M}{a}

Consider the logarithm base b of both sides:

x = \log_b\left(\dfrac{e^M}{a}\right)

The two numbers are the same: you can check it using the rule for changing the base of logarithms

Galina-37 [17]

Answer:T

Step-by-step explanation: Every Input should correspond to exactly one output. Every input should only have one output. If 2 outputs correspond to the same # for the input, then it is not a function like in this example where 4 and -4 correspond to one input # which is 3 and the same with the 5's
