a father is 27 years older than his son. ten years ago he was twice as old as his son. how old is the father

A = allowance
(1/2)a = what have left after Monday
(1/2(1/2)a = what you have after Tuesday
(1/2)(1/2)(1/2)a = what you have after Wednesday.

Doing the multiplication.

(1/8)a = what you have left.

You have 1/8 of what you had at the start.

It would be 50 times because 15 divided by 3 is 5 and you just add your 0 back and get 50! hope this helps!

Condensing Logarithmic Expressions In Exercise, use the properties of logarithms to rewrite the expression as the logarithm of a

yKpoI14uk [10]

Answer:

$4ln [\frac{x^2 (x^3-1)}{x-5}]$

Step-by-step explanation:

For this case we have the following expression:

$4[ln(x^3-1) +2ln(x) -ln(x-5)]$

For this case we can apply the following property:

$a log_c (b) = log_c (b^a)$

And we can rewrite the following expression like this:

$2 ln(x) = ln(x^2)$

And we can rewrite like this our expression:

$4[ln(x^3-1) +ln(x^2) -ln(x-5)]$

Now we can use the following property:

$log_c (a) +log_c (b) = log_c (ab)$

And we got this:

$4[ln(x^3-1)(x^2) -ln(x-5)]$

And now we can apply the following property:

$log_c (a) -log_c (b) = log_c (\frac{a}{b})$

And we got this:

$4ln [\frac{x^2 (x^3-1)}{x-5}]$

And that would be our final answer on this case.
