Answer:

$\displaystyle E=26log2-24log3+8log 5$

Step-by-step explanation:

<u>Logarithms</u>

There are certain properties of the logarithms we'll need to recall in order to simplify the expression given in the question. We'll list them below

$log(x.y)=logx+logy\\log(x/y)=logx-logy\\logx^y=y.logx$

We'll also need to factor the following numbers into their prime factors:

$20=2^2\cdot 5$

$16=2^4$

$15=3\cdot 5$

$25=5^2$

$24=2^3\cdot 3$

$81=3^4$

$80=2^4\cdot 5$

The original expression is

$\displaystyle E=log20+16log\frac{16}{15}+12log\frac{25}{24}+log\frac{81}{80}$

Plugging in the factored values

$\displaystyle E=log(2^2\cdot 5)+16log\frac{2^4}{3\cdot 5}+12log\frac{5^2}{2^3\cdot 3}+log\frac{3^4}{2^4\cdot 5}$

Applying the properties we have

$\displaystyle E=log2^2+log 5+16(log2^4-log3-log 5)+12(log5^2-log2^3-log 3)+log3^4-log2^4-log 5$

$\displaystyle E=2log2+log 5+16log2^4-16log3-16log 5+12log5^2-12log2^3-12log 3+log3^4-log2^4-log 5$

$\displaystyle E=2log2+log 5+64log2-16log3-16log 5+24log5-36log2-12log 3+4log3-4log2-log 5$

Simplifying

$\boxed{\displaystyle E=26log2-24log3+8log 5}$

Help me solve those show work 3(2a-5)=12-7a, 27=3c-3(6-2c)and 6c-8-2c=-16

Nadusha1986 [10]

1) 3(2a-5)=12-7a

First distribute the 3. This leaves you with 6a-15=12-7a.

Now, add 15 to both sides. This leaves you with 6a=27-7a.

Now, add 7a to both sides. This leaves you with 13a=27.

Now, you can finally divide 13a on both sides. This leaves you with a=27/13

2) 27=3c-3(6-2c)

First, distribute the 3.This leaves you with 27=3c-18+6c

Now, combine like terms/simplify. This leaves you with 27=9c-18.

Now, add 18 to both sides. This leaves you with 45=9c.

Now, you can finally divide 9 on both sides. This leaves you with 5=c.

Lastly, use the reflexive property. This leaves you with c=5.

3) 6c-8-2c=-16

First, combine your like terms. This leaves you with 4c-8=-16.

Now, add 8 to both sides. This leaves you with 4c=-8.

Now, divide 4 on both sides. This leaves you with c=-8/4.

Finally, you can simplify the fraction. This leaves you with c=-2.
