If y = 4 + 0.10x, then what is y if x=20?

y = 4 + 0.10 * 20   =    4 + 2    =  6

If you use this expansion, it will give you 50% more digits:

(1 + 1/10^100)^(10^100.5)

pi times radius squared

We can find this as follows :

[ (-3061) mod 360]°  = 179°

P.S. - you can find an app to do this here :

Assuming that you are looking for a numerical value,write out the series   for e^x

and then put  x=1 .The series converges very quickly so you don't need to take many terms to get an accurate value. 

that is e^x = 1 + x + (x^2)/2!  + (x^3)/3!   etc etc  ....  and just plug in  x=1

better then yours lml wrekkkt boi 

If you mean the problem as written:  1 / 1 / 2  =  (1 / 1) / 2  =  1 / 2.

However, if you mean it to be:  1 / (1/2), then ElectricPavlov has the answer.

Compare Melody's solution to this step-by-step solution by Wolfram/Alpha!. I think Melody's solution is more elegant than W/A!!. So winded!!.

Solve for N over the real numbers:
-10000+40396.2 1.07^(-N)-21428.6 (1-1.07^(-N)) = 0

-10000+40396.2 1.07^(-N)-21428.6 (1-1.07^(-N)) = -10000+201981 (4/107)^N 5^(2 N-1)-150000/7 (1-(100/107)^N):
-10000+201981 (4/107)^N 5^(2 N-1)-150000/7 (1-(100/107)^N) = 0

Factor 107^(-N) and constant terms from the left hand side:
1/35 107^(-N) (1413867 4^N 5^(2 N)+3 4^(N+2) 5^(2 N+6)-1100000 107^N) = 0

Multiply both sides by 35:
107^(-N) (1413867 4^N 5^(2 N)+3 4^(N+2) 5^(2 N+6)-1100000 107^N) = 0

Split into two equations:
107^(-N) = 0 or 1413867 4^N 5^(2 N)+3 4^(N+2) 5^(2 N+6)-1100000 107^N = 0

107^(-N) = 0 has no solution since for all z element R, 107^z>0:
1413867 4^N 5^(2 N)+3 4^(N+2) 5^(2 N+6)-1100000 107^N = 0

4^N 5^(2 N) = e^(log(4^N)) e^(log(5^(2 N))) = e^(N log(4)) e^((2 N) log(5)) = e^(2 N log(5)+N log(4)) and 4^(N+2) 5^(2 N+6) = e^(log(4^(N+2))) e^(log(5^(2 N+6))) = e^((N+2) log(4)) e^((2 N+6) log(5)) = e^((N+2) log(4)+(2 N+6) log(5)):
-1100000 107^N+1413867 e^(2 log(5) N+log(4) N)+3 e^(log(4) (N+2)+log(5) (2 N+6)) = 0

Divide both sides by 107^N:
2163867 107^(-N) e^((log(4)+2 log(5)) N)-1100000 = 0

Bring 2163867 107^(-N) e^(N (log(4)+2 log(5)))-1100000 together using the common denominator 107^N:
-107^(-N) (1100000 107^N-2163867 e^((log(4)+2 log(5)) N)) = 0

Multiply both sides by -1:
107^(-N) (1100000 107^N-2163867 e^((log(4)+2 log(5)) N)) = 0

Split into two equations:
107^(-N) = 0 or 1100000 107^N-2163867 e^((log(4)+2 log(5)) N) = 0

107^(-N) = 0 has no solution since for all z element R, 107^z>0:
1100000 107^N-2163867 e^((log(4)+2 log(5)) N) = 0

Divide both sides by e^(N (log(4)+2 log(5))):
1100000 107^N e^((-log(4)-2 log(5)) N)-2163867 = 0

107^N e^(N (-log(4)-2 log(5))) = e^(log(107^N)) e^(log(e^(N (-log(4)-2 log(5))))) = e^(N log(107)) e^((N (-log(4)-2 log(5))) log(e)) = e^(N log(107)+N (-log(4)-2 log(5))):
1100000 e^(log(107) N+(-log(4)-2 log(5)) N)-2163867 = 0

Add 2163867 to both sides:
1100000 e^(log(107) N+(-log(4)-2 log(5)) N) = 2163867

Divide both sides by 1100000:
e^(log(107) N+(-log(4)-2 log(5)) N) = 2163867/1100000

Take the natural logarithm of both sides:
log(107) N+(-log(4)-2 log(5)) N = log(2163867/1100000)

Expand and collect in terms of N:
(-log(4)-2 log(5)+log(107)) N = log(2163867/1100000)

Divide both sides by -log(4)-2 log(5)+log(107):
Answer: | N = (log(2163867/1100000))/(-log(4)-2 log(5)+log(107))=10

There are online RPN calculators; one is at http://www.alcula.com/calculators/rpn/

√403  ≈  20.0748

No, it doesn't use RPN system. That is, almost always, confined to HP calculators.

1  /    1/2   =   1  x  2/1 = 2

Not sure what you INTENDED to ask, but here are a few possibilities

210 hr   x  1 day/24hr  = 8.75 days

210 hr   x 60 min/hr     = 12,600 minutes       

210 hr   x 60 min/hr  x 60 sec/min= 756,000 sec

10th term = F + d(n-1)

                = 1 + 8(10-1)

                = 1 + 72

                = 73

The point begin ordered pair, negative 2, 3, end ordered pair is the solution to which of the following systems of equations?

5^(2*x+7)-25^(2*x)

What do you want done with this - I have factorised it.

\(5^{2x+7}-25^{2x}\\ =5^{2x+7}-(5^2)^{2x}\\ =5^7*5^{2x}-(5^{2x})(5^{2x})\\ =5^{2x}(5^7-5^{2x})\\ =25^{x}(5^7-25^{x})\\\)

You just type it with a slash (/). So if you wanted to type in two thirds, it would be 2/3 and the calculator will turn it into a fraction at the top.

Beats me

whats the square root of 24?

\(\sqrt{24}=\sqrt{4*6}=\sqrt4*\sqrt6=2\sqrt6\)

64c^3-125/5-4c=?

\(64c^3-125/5-4c\\ =64c^3-25-4c\\\)
