Q. Write the expression below as a single logarithm in simplest form.logb10−logb10Answer: logb(□)
Identify Property: Identify the property used to combine the logarithms.The expression given is logb(10)−logb(10), which involves the subtraction of two logarithms with the same base.The subtraction of logarithms corresponds to the division of their arguments according to the quotient property of logarithms.Quotient Property: logb(P)−logb(Q)=logb(QP)
Apply Quotient Property: Apply the quotient property to combine the logarithms.Using the quotient property, we can write the expression as a single logarithm:logb(10)−logb(10)=logb(1010)
Simplify Argument: Simplify the argument of the logarithm.The argument of the logarithm simplifies to:1010=1So, the expression becomes logb(1).
Recognize Logarithm Value: Recognize the value of the logarithm of 1. The logarithm of 1 to any base is always 0 because any number raised to the power of 0 is 1. Therefore, logb(1)=0.
