I will assume you mean the 11th root of  e

using the calculator,

\(\sqrt[11]{e}\) = 1.0951694398746643

There are infinite values for 'x' and 'y' if you have two variable and only ONE equation

to find a discrete (x,y) solution you will need two equations relating x and y.

Do the exponentiation first to get

2 x 4  +  3 x 2 x -4 x -4 x 16     then step two is do the multuplication

8        +      1536

1544

This shows the importance of parentheses and brackets which are often left out of questions on this forum.  Usually you can discern what was MEANT even if it is asked improperly, but not always.

To me 

  48/2(9+3) = 48/2   x   (9+3)     = 288   

   It does NOT equal  48/(2(9+3)) though that is what perhaps was MEANT (but NOT written)

I answered a VERY similar question as this yesterday:

I think the formula you need  is:

For the FIRST card   P = 6230

A = P( i (1+i)^n / ((1+i)^n-1)    A = monthly payment   n = 36 payments   i = periodic interest in decimal = 20.4/12=.017

For the SECOND card  P = 2960   i = .0234 

Substitute into the equation for EACH card then add the results together for her total monthly payment ...

Got it?    Need more help?

Thanx for the confirmatio, Chris.....I'm a little weak at probability and statistics, hence I did not include my calculations.....but they were correct (THIS time).....so I 'guessed'  ....  some day I will be up to speed !

48.7 percent?

I THINK we need the mass of the metal bar to compute this value....

Ooops    sorry for my incorrect spelling....

'complimentary'   should be 'complementary'.......BOTH times     Haha

kg/m  /  kg/m^3     to divide fractions, flip the bottom one and MULTIPLY

kg/m  x  m^3/kg    the ' kg s '  and ONE of the 'm s'  cancel and you are left with m^2

1x 1 = 1       answer is   1 m^2
