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

The perimeter of a rectangle is 20 inches.The length is 2 inches less than twice the width.
SSSSS [86.1K]

Answer:

width = 6

length = 4

Step-by-step explanation:

perimeter = 2L + 2W

L = W - 2

plug in perimeter:

20 = 2L + 2W

you know the length is 2 less than the width

plug in (w - 2) for L:

20 = 2(w - 2) + 2w

solve for w:

20 = 2w - 4 + 2w

20 = 4w - 4

4w = 24

w = 6

now plug in 6 for w in either equation, whichever is easier to solve:

L = 6 - 2

L = 4

width = 6

length = 4
