Answer 1
Answer:

Using exponential and logarithmic functions, it is found that:

a) The solution of the inequality ln((x)) < 0 is (-infty, 1).

b) The solution of the inequality e^x > 2 is (ln(2), \infty)

a) The solution to the equation ln((3x - 17)) = 5 is x = 55.14.

As a single logarithm, the expression is:

\ln{\left((a^2 - b^2)/(c^5)\right)}

Inequality a:

ln((x)) < 0

Applying the exponential to both sides:

e^(ln((x))) < e^(0)

x < 1

Hence, in interval notation:

(-infty, 1)

Inequality b:

e^x > 2

Applying ln to both sides:

ln(e^x) > ln(2)

x > ln(2)

Hence, in interval notation, the solution is:

(ln(2), \infty)

Equation a:

ln((3x - 17)) = 5

e^(ln((3x - 17))) = e^5

3x - 17 = e^5

3x = 17 + e^5

x = (17 + e^5)/(3)

x = 55.14

The quantity given is:

ln((a + b)) + ln((a - b)) - 5ln(c)

To express as a single logarithm, these following properties are applied:

ln(a) + ln(b) = ln(ab)

ln(a) - ln(b) = \ln{\left((a)/(b)\right)}

aln(b) = ln(b^a)

Hence:

ln((a + b)) + ln((a - b)) - 5ln(c) = ln((a + b)(a - b)) - ln(c^5)

As a single logarithm, the expression is:

\ln{\left((a^2 - b^2)/(c^5)\right)}

Answer 2
Answer:

Answer:

(a) ln(x) = 0

Then 0 < x < 1

(b) e^x > 2

Then ln2 < x < ∞

(a) ln(3x - 17) = 5

x = 55.1377197

ln(a + b) + ln(a - b) - 5ln(c)

= ln[(a² - b²)/c^5]

Step-by-step explanation:

First Part.

(a) ln(x) < 0

=> x < e^(0)

x < 1 ....................................(1)

But the logarithm of 0 is 1, and the logarithm of negative numbers are undefined, we can exclude the values of x ≤ 0.

In fact the values of x that satisfy this inequalities are between 0 and 1.

Therefore, we write:

0 < x < 1

(b) e^x > 2

This means x > ln2

and must be finite.

We write as:

ln2 < x < ∞

Second Part.

(a) ln(3x - 17) = 5

3x - 17 = e^5

3x = 17 + e^5

x = (1/3)(17 + e^5)

= 55.1377197

Third Part.

We need to write

ln(a + b) + ln(a - b) - 5ln(c)

as a single logarithm.

ln(a + b) + ln(a - b) - 5ln(c)

= ln(a + b) + ln(a - b) - ln(c^5)

= ln[(a + b)(a - b)/(c^5)]

= ln[(a² - b²)/c^5]
