There is no single solution.Taking logs: alog3=blog5 and blog5=clog75 If alog3=blog5=t then a=t/log3, b=t/log5 leading to c=t/log75. Then ab-c(2a+b) =t^2/(log3log5) - (t/log75)(2t/log3+t/log5) =t^2[ 1/(log3log5) - (1/log75)[2log5+log3]/(lo3log5) =t^2[1/(log3log5) - (1/log75)[log75]/(log3log5) =t^2[ 1/(log3log5) - 1/(log3log5)] =0

Problem Statement:

If 3^a = 5^b = 75^c, then what is the value of ab - c(2a + b)?

Solution:

Given: 3^a = 5^b = 75^c

We can rewrite 75 as 3^1 * 5^2, so the equation becomes:

3^a = 5^b = (3^1 * 5^2)^c

Now, we can rewrite this equation as:

3^a = 3^c * 5^2c (using the property of exponents)

Since the bases are the same, the exponents must be equal:

a = c + 2c

Simplifying the above equation, we get:

a = 3c

Similarly, we can rewrite the equation as:

5^b = 3c * 5^2c

Again, equating the exponents:

b = 2c

Calculating the value of ab - c(2a + b):

ab - c(2a + b) = (3c)(2c) - c(2(3c) + 2c)

= 6c^2 - c(6c + 2c)

= 6c^2 - c(8c)

= 6c^2 - 8c^2

= -2c^2

Hence, the value of ab - c(2a + b) is -2c^2.

Summary:

The value of ab - c(2a + b) reduces to -2c^2.
