What is two n squared by two???

What's 2n squared I'm confused,

2n means 2 X n, Now multiply each by itself like this:

2 X 2=4, that's the same as "2 squared", and do the same with n, or

n X n=n^2. Now put them together like this:

2n squared=4n^2

Your question is a bit ambiguous when you convert it from written symbols into a kind of "spoken" equivalent.

There are two possibilities for what your spoken equivalent corresponds to:

• 2n² would be the most likely because the exponent operation takes precedence over the multiplication (you'd square n before multiplying by 2), so that's 2 · n · n
• (2n)² would be spoken as "2 n quantity squared" where the quantity implies that 2n is in parentheses. In this case, the whole expression is multiplied by itself, so 2 · n · 2 · n or 4n².

What is two n squared by two???the answer should equal -144.I'm trying to solve for n.

the maximum number of electrons present in a shell is given by the formula 2n squared, where n is the orbit number or energy level index

2n sqaured is a term used in quadratic sequences, n sqaured is just the normal square numbers, so 2n squared is just them doubled
