68ac^3 divided by the square root of 27a^2
√ [ 68ac^3] / √[27a^2] .... we have
√[68/27] * √[a/a^2] *√c^3 =
(4/3) √(17/3) * √[a/a^2] *√c^3 =
(4/3) √(17/[3a]) * c√c =
(4c/3)√(17c/[3a])
Except for 0/0, you are correct {0/0 is known as an "indeterminate" form }
Just put this into the onsite calculator, garmoon.....
There volume of a sphere {in this case, a baskeball} is given by
V = (4/3) pi r^3 where r is the radius ...so we have...
v = (4/3) pi (4)^3 = about 268.1 in^3 { rounded to nearest tenth }
Post your questions, Ben....we'll see what we can do.....
maby 8 p.s are you in a class room?
hi everone
1/13=? that what i got
i do not know, please help me
Well maybe you should ask Siri
Hi i'm Kevin Zhang
1x10^-6=1x(1/10^6)=1x(1/1000000)=1/1000000 or 0.000001
I'm Ready for you ;)
Hi I'm Kevin Zhang AMA
is it compound or analual?
Be careful here......this is a common mistake to assume that -5^2 = 25......!!!!
-5^2 = -1(5)(5) = -25 the exponent only applies to the 5, NOT to the "understood" -1 preceding 5
However......
(-5)^2 = (-5) (-5) = (-1 * 5) (-1* 5) = (-1 * -1) (5 * 5) = (1) (25) = 25
See the difference???
Absolute value is just the distance between a particular number and 0 on the number line....
So... abs(pi) = l pi l = pi ..... since it's "pi" units from 0...!!!
Don't get confused here, MG1.....
1! + 2! + 3! + ..... + 1393! is a shorthand notation for summing all the integer factorials from 1 to 1393.....{there are 1393 terms to be summed !!}
I don't know what this sum might be, because 1393! by itself would "wreck" our calculator....{the sum is not infinity, however......but definitely a HUGE number.... }
$${\mathtt{1\,393}}{!} = \infty$$
$${\mathtt{1}}{!}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}}{!}{\mathtt{\,\small\textbf+\,}}{\mathtt{3}}{!} = {\mathtt{9}}$$
The answer is 9 + infinity = Infinity.
(Based on the calculator)
The answer is 19 and if you want to joke about it, It's 19.
Make that 4!
And there are some users that are just 'awesome'...Like Melody and CPhill who answer quickly and they really do help you understand!
the answer to your question is 19
Well....if you're referring to math, maybe we can help......post your question(s)......
Nice answer, Mathcad....!!!
Example
x^2 - 10x + 25 = 0
x = [ -b ± √[b^2 - 4ac ] / [2a]
x = [ 10 ± √[(-10)^2 - 4(1)(25)] / [2(1)] =
x = [10 ± √[100 - 100] / 2 =
x = 10 / 2 = 5
