Stwp by step please what is the value of n 1.8×10^n=(6×10^8)(3×10^6)

1 answer:

5 0

1.8×10^n=(6×100,000,000)×(3×1,000,000)
1.8×10^n=600,000,000×3,000,000
1.8×10^n=1,800,000,000,000,000
Divide both sides by 1.8
10^n=1,000,000,000,000,000
There are 15 0's, so n=15

. Write each number in terms of natural logarithms, and then use the properties of logarithms to show that it is a

siniylev [52]

Answer:

The answer is 3/4

Step-by-step explanation:

Hi, we need to change the base of the logarithm, for that we need to use the following formula.

$Log_{b} (a)=\frac{Ln(a)}{Ln(b)}$

In our case, this is:

$Log_{9} (\sqrt{27} )=\frac{Ln(\sqrt{27} )}{Ln(9)}$

Which is the same as:

$\frac{Ln(27)^{\frac{1}{2} }}{Ln(9)}$

Now, let´s solve this using the log properties

$\frac{1}{2} (\frac{Ln(27)}{Ln(9)} )$

$\frac{1}{2} (\frac{Ln(9*3)}{Ln(9)} )$

$\frac{1}{2} (\frac{Ln(9)+Ln(3)}{Ln(9)} )$

$\frac{1}{2} (\frac{Ln(9)}{Ln(9)}+\frac{Ln(3)}{Ln(9)} )\\$

We can change 3 for 9^(1/2)

$\frac{1}{2} (\frac{Ln(9)}{Ln(9)}+\frac{Ln(9^{\frac{1}{2} } )}{Ln(9)} )\\$

$\frac{1}{2} (\frac{Ln(9)}{Ln(9)}+\frac{Ln(9 )}{2*Ln(9)} )\\$

Since Ln(9) / Ln(9) =1, we get.

$\frac{1}{2} (1+\frac{1}{2} )$

$\frac{1}{2} (\frac{3}{2} )=\frac{3}{4}$

Best of luck.

What is the answer for part b??

nasty-shy [4]

If you factor the expression of part A, you will get the expression of part B

the reason is that the perimeter of a rectangle is equal to 2(l+w)

so in the factorization number 2 will be multiplied by the rest of the expression

good luck
