To divide deciamals, you move the decimals over until you can divide easily.

Here's some examples:

The important thing to remember is that you have to move the decimal over in both the thing your dividing by, and the thing your dividing.

Then just carry the decimal up to your answer, and wala!

Yep...I agree

Waffles???......Yum!!!!

Save me some.......

i think anonymous forgot some signs that were to be placed in between!

rosala.....I don't know what this is, either.......

I'm assuming that we have monthly compounding.......so we have......

650 = P(1 +.03/12)⁽⁴⁵⁾

Divide both sides by  (1 +.03/12)⁽⁴⁵⁾

P = 650/(1 +.03/12)⁽⁴⁵⁾ ≈ $580.92

So would u like to have some "anonymous"!

Waffles!

i think a troll question!

CPhill or anyone else if u know anything about this question can u please tell me!ive never seen such expressions : 26xy23, what are these!?

$$So this looks like:\\
$\frac{x+1}{1}$\\
I'm not sure what you want us to do with this. Simplify maybe?\\
You could simplify by taking the 1 on bottom away, because that isn't really necessary.\\
This would then simplify to:\\
$x+1$$$

It's the  x^y  key.....

44118 = 3^b mod 65537

This says that

65537n + 44118 = 3^b

There are infinite solutions to this...for instance....

Let n=3

Then we have

240729 = 3^b

Taking the log of both sides, we have

log 240729 = log 3^b    .....and by a property of logs, we have

log 240729 = b*log3    ......and dividing both sides by log3, we have

log 240729/log 3  = b ≈ 11.2791630188882364

If we insist that both n and b be integers, I'm not sure how to solve this....(if it even has a solution).....(maybe Alan knows a method)

So to find the total amount of money that Siti and her brother have we will add the two amounts and so that will give us the total amount they both together have!so we will do it like this!

$$123.75 + 189.50$$  (and now we will simply add them both)

$$=313.25$ ANSWER$$ 

So Siti and her brother have totally saved RM313.25

I hope u have understood by now but if not then pls be free to ask!

hope it helps!

Take logs of both sides:  ln(44118) = ln(3^b)

From a property of logs we have ln(3^b) = b*ln(3) so ln(44118) = b*ln(3); hence b = ln(44118)/ln(3)

$${\mathtt{b}} = {\frac{{ln}{\left({\mathtt{44\,118}}\right)}}{{ln}{\left({\mathtt{3}}\right)}}} \Rightarrow {\mathtt{b}} = {\mathtt{9.734\: \!665\: \!497\: \!315\: \!512\: \!4}}$$

Because you have arithmetic mod 65537, you could find other answers by adding multiples of 65537 on to 44118 first.  For example

$${\mathtt{b2}} = {\frac{{ln}{\left({\mathtt{44\,118}}{\mathtt{\,\small\textbf+\,}}{\mathtt{65\,537}}\right)}}{{ln}{\left({\mathtt{3}}\right)}}} \Rightarrow {\mathtt{b2}} = {\mathtt{10.563\: \!412\: \!108\: \!297\: \!925\: \!2}}$$

$$\left({{\mathtt{3}}}^{\left({\frac{{ln}{\left({\mathtt{44\,118}}{\mathtt{\,\small\textbf+\,}}{\mathtt{65\,537}}\right)}}{{ln}{\left({\mathtt{3}}\right)}}}\right)}\right) {mod} \left({\mathtt{65\,537}}\right) = {\mathtt{44\,117.999\: \!999\: \!999\: \!96}}$$

(A small numerical error creeping in there!)

4(2^(n-1))=16ⁿ

And we can write  4 as 2²  and 16 as 2⁴.....and we have....

2²(2^(n-1))=(2⁴)ⁿ    ........and, by a property of exponents, we have

2^{(2 + n - 1)} = 2⁽⁴ⁿ⁾

2^{( n + 1)} = 2⁽⁴ⁿ⁾

And solving for the exponents, we have

n + 1  = 4n

1  = 3n

n = 1/3

$$This can be written as $$2^2\times2^{n-1}=(2^4)^n$$\\\\
or $$2^{n+1}=2^{4n}$$\\\\
In other words $n+1=4n$ or $n=\frac{1}{3}$$$

this is just algebra CPHill. dont be so hard on yourself!

(-3s²t)⁴ =

(-3)⁴ * (s²)⁴ * t⁴  =

81s⁸t⁴

im sorry but i  dont understand your question!

 i think the day has ended a lil too early today!but remember the Queen can do anything!

And for real life:Melody you'll surely be missed!but no problem as you wish , i thought i could take your place but i think CPhill is already in front of me in line for that!lol!

T(t) = T_A + (T_H - T_A)e^-kt

where,

T(t) = Temperature at time t,
T_A = Ambient temperature (temp of surrounding)
T_H = Initial temperature of the cake
k = constant of proportionality (negative because of cooling)
t = time.

Now, for A, we have,

120 = 70 + (180 - 70)e^-kt, or $$\frac{}{}$$e^-kt = 5/11

For B, i.e. to find t, you need k.

22)....I'm not a Physics major (or even minor!! ) but this one is based on Newton's Law of Cooling.......I don't believe we can answer the question unless we know how long it took for the center to cool from 180F to some lesser temperature.....we have to know this in order to find the constant of proportionality.....(Alan can correct me, if I'm wrong!!) ..also...is 120F the desired temperature??

----------------------------------------------------------------------------------------------------

28)   This is given by     A = Pe^(rt)   where A is the accumulated amount, P is the amount invested, r is the interest rate (as a decimal) and t is the time....so we have....

A = 2000e^(.051*3) = about $2330.65
