algol [13]

Answer:

I don't know what the following sentence is:

But D is the equation to represent the situation

and A is what turns out to be his current age.

(If you want more help, on this question please post the following sentence).

Step-by-step explanation:

Let x represent the current age.

15 years from now his age is 3 times his age 5 years ago means we have the equation:

x+15=3(x-5)

(I added x to 15 because we said 15 years in the future)

Let's solve this to see if makes any sense just for fun:

Distribute:

x+15=3x-15

Add 15 on both sides:

x+30=3x

Subtract x on both sides:

30=2x

Divide both sides by 2:

15=x

So this means his current age is 15.

5 years ago his age would have been 10.

15 years in the future his age will be 30.

Is 30 equal to 3 times 10? Yes, it is! The equation does make sense.

Rewrite 34 = 81 in logarithmic form.

Anna35 [415]

Answer:

$log_3(81) = 4$

Step-by-step explanation:

Given

$3^4 = 81$

Required

Rewrite in logarithmic form

We start by taking log of both sides

$3^4 = 81$

$log3^4 = log81$

From laws of logarithm;

$loga^b = b\log(a)$

So; $log3^4 = log81$ becomes

$4log3 = log81$

Divide both sided by log3

$\frac{4log3}{log3} = \frac{log81}{log3}$

$4 = \frac{log81}{log3}$

From laws of logarithm;

$\frac{loga}{logb} = log{_b}(a)$

So;

$4 = \frac{log81}{log3}$ becomes

$4 = log_3(81)$

$log_3(81) = 4$

Hence, $3^4 = 81$ in logarithm form is $log_3(81) = 4$
