In order to solve this, We will want to change it into an exponential form. Assuming that since we do not have a number beside log, It will be log base 10.


10^4=x

We can now solve for x.

This means that x= 10,000

Answer:

x=10000

Step-by-step explanation:

We want to solve the logarithmic equation;


log(x)=4


Since no base is written, the given logarithm is in base 10.


We can rewrite the equation as


log_{10}(x)=4


We take the antilogarithm of both sides to base 10 to obtain;


10^{log_10(x)}=10^4


This implies that;


x=10^4


\Rightarrow x=10\times10 \times10 \times 10


\Rightarrow x=10000

Finding the volume of a cube involves multiplying with this formula.

Height * Width * Length = volume

To find what the side lengths are, we can take the cube root of 64.

∛64 = 4

Height = 4

Width = 4

Length = 4

These sides are multiplied together to get 64.

The only answer choice that makes sense is Option A.

The expression (3x - 2)/(x + 4) = 0 has a value of x is 3/2. Amd the expression 2/(x + 4) = 0 has a value of x is ∞.

<h3>What is simplification?</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

The expression is given below.

(3x - 2)/(x + 4) = 0

Then on simplifying, we have

3x - 2 = 0

    3x = 2

      x = 3/2

And

2/(x - 3) = 0

         2 ≠ 0

More about the simplification link is given below.
