Solve log x = 2.

Mathematics
1 answer:

Answer:

If log x = 2

x = 100

Step-by-step explanation:

Logarithm always has a base and an index. It can be I many forms.

It can be in base 2, 3, 4, 5, and so on.

It is a property of logarithm that if

logarithm of 'a' to base 'b' equals 'x', we write:

log_b (a) = x

Then,

a = b^x.

Usually, when a logarithm is written without a base, it tells us that it is in base 10. Instead of writing a logarithm of x to base 10,we can just write 'log x', it is sufficient to say that it is in base 10.

It can also be in the form of the Napierian Logarithm, 'ln'.

'ln x' is logarithm to base 'e'.

if ln x = 5

Then

x = e^5.

So,

log x = 2

Means logarithm of 'x' to base 10 equals 2.

x = 10^2

= 100

x = 100

you bought 4 bananas and 5 apples at the store for $2.50 the next day you bought 10 bananas and 3 apples at the store for $3.40.
PIT_PIT [208]
Bananas cost: $0.25 
Apples cost: $0.30

4b+5a=2.50
10b+3a=3.40 
You multiply the equations by the variables so they can cancel out. For example the first one by 3 and the second by 5 so you have

12b+15a=7.50
50b+15a=17
Subtract them and end up with

-38b=-9.5 
solve: b=0.25, substitute b in any equation and get a=0.30

To multiply rational expressions you just multiply tops and multiply the bottoms so
5/2x+1  *  6/x = 30/2x^2+x

On a quiz show, Linda won $10 less than three times as much as Charlie. If Linda won $800, how much did Charlie win?
PilotLPTM [1.2K]

Using a system of equations, it is found that Charlie won $270.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable x: Amount earned by Linda.
  • Variable y: Amount earned by Charlie.

Linda won $10 less than three times as much as Charlie, hence:

x = 3y - 10

Linda won $800, hence the amount won by Charlie is found as follows:

800 = 3y - 10

3y = 810

y = 810/3

y = 270
