Solving for variables is easy as all we must do is isolate the variable and simplify. In this case, to isolate the variable, we simply need to divide "n" by 10 (because the "n" is being multiplied by 10).

10n=40
/10 /10
n=4

Using the math above, we can see that n=4.

What is the following logarithmic equation in exponential form: <br><br> log2(x^4 -3) = 4

Harman [31]

Answer:

$2^{4}$ = $x^{4}$ - 3

Step-by-step explanation:

recall for a logrithimic expression,

$log_{b}$ (c)=a, can be expressed as $b^{a} = c$

hence for our question

$log_{2}$ [ (x^4) -3] = 4

can be expressed as

$2^{4}$ = $x^{4}$ - 3
