Let a = log 2 , b = log 3 , and c = log 7 . In Exercises 29–46, use the logarithm identities to express the given quantity in terms of a , b , and c . log 28

To determine

To calculate: The given quantity, log28 in term of a, b and c.

Explanation

Given information:

The given value of a, b and c is,

a=log2, b=log3 and c=log7

Formula used:

The logarithmic identity,

loga(mn)=logam+logan

Here, a, m and n are real number.

Calculation:

Consider the quantity, log28

Number 28 can be written as product of 2, 2 and 7

log28=log(227)

Now apply the logarithmic identity, loga
