How do I find #2/3# of a whole number? - Socratic
2017年2月11日 · To find 2/3 of a whole number, you need to multiply the number by the numerator 2 and divide that product by the denominator 3. If you represent any whole number by n; then 2/3 of that number is 2/3 n, or (2n)/3 Looking at the last form you can see that you are multiplying the number n by 2 and dividing the product by 3. Example if: n = 666 2/3 xx n = 2/3 …
How do you evaluate the power 2^3? - Socratic
2016年10月26日 · When evaluated, 2^3 equals 8. See Explanation. 2^3 means 2* 2* 2. In order to evaluate, you need to write your problem out as 2* 2* 2 then solve it out. 2* 2* 2= 8 So the evaluation of 2^3 is 8 Hope this helps!
How do you factor x^3-3x+2? - Socratic
2015年5月31日 · First notice that substituting x=1 results in x^3-3x+2 = 0 So (x-1) is a factor. Use synthetic division to find the remaining factor... x^3-3x+2 = (x-1)(x^2+x-2) Notice that x=1 is also a root of x^2+x-2 So we have another (x-1) factor... x^2+x-2 = (x-1)(x+2) So the complete factorization is: x^3-3x+2 = (x-1)(x-1)(x+2)
How do you sum the series 1+a+a^2+a^3+...+a^n? - Socratic
2015年7月3日 · 1+a+a^2+a^3+...+a^n = (1-a^(n+1))/(1-a) (1+a+a^2+a^3+...+a^n)(1-a)=1-a^(n+1) Divide both sides by (1-a) to get: 1+a+a^2+a^3+...+a^n = (1-a^(n+1))/(1-a)
How do you write x^(2/3) in radical form? - Socratic

How many electrons are in n=3, l= 2? - Socratic
2017年6月12日 · "10 e"^(-) The idea here is that you must use the value of the angular momentum quantum number, l, which tells you the energy subshell in which an electron resides, to find the possible values of the magnetic quantum number, m_l. The number of values that the magnetic quantum number can take tells you the number of orbitals that are present in a given …
Condensed Structure - Organic Chemistry - Socratic
Condensed structure formulas are also an efficient way to identify a chemical compound. Instead of drawing it out, the structure utilizes the elemental symbols to indicate the number of carbons and the bonded molecules. CH₃CH₂OH is a condensed organic formula.

What are the names of the isomers for C4H8Br2? - Socratic
2015年11月24日 · The 2,3-dibromobutane would have free bond rotation about the C2-C3 bond, which is indicated with the "resonance" double arrow. The general process was to shift the bromide around while taking symmetry into account, and then shift the methyl around while accounting for symmetry, and fill in any gaps you have left. Names: 1,4-dibromobutane
