I guess you want the constant term for......

$$$\Big(x^2+\frac{1}{x}\Big)^4$$$

There is no constant term here, Mellie.....notice the expansion....

I assume you want the "inverse" of this  ???

y = 1.029^x + 2.25   subtract 2.25 from both sides

y - 2.25  = 1.029^x    take the log of both sides

log [ y - 2.25] = log 1.029^x     and we can write

log [ y - 2.25 ] = x log 1.029     divide both sides by log1.029

log [ y - 2.25 ] / log 1.029  = x    "exchange" x and y

log [ x - 2.25 ] / log 1.029   = y    and for y, we can write  f^-1(x)

So the inverse is

 f^-1(x)  = log [ x - 2.25 ] / log 1.029

 (3^-2)^3 divided by 3^-2

(3^-2)^3  = 3^-6

So

[ 3 ^-6 ] / {3 ^ -2] =

[3 ^2 ] / [ 3^6]  =

1 [ 3^4] =

1 / 81

An off the cuff" definition is : The locus (set) of points in a plane that are equidistant from a point in that plane - known as the focal point -  and a line - known as the directrix.....

It's NOT 15 mph  {as many people would think !!!}

There's an easy "formula" for this:

[2(R₁)(R₂)] / [ R₁ + R₂ ]       where R₁ and R₂ are the rates   ... so we have

[2(10)(20)] / [10 + 20]  =

400 / 30  =

about 13.33  mph

We have :

6° 14' 48"

Since there are 60 minutes in each degree  ...  14 of them = 14/60

And there are  3600 seconds in each degree..... so,  48 of them = 48/3600 

So.

[ 6 + 14/60 + 48/3600]°  =  about 6.24666°

m=3n+2p      subtract 3n from both sides

m - 3n = 2p   divide both sides by 2

[m - 3n ] / 2   = p

Division by 0 is undefined......!!!!

How do you see the difference between a house and yard to calculate?

To calculate what??
