Arrange the following data as an array (descending order):

9.1, 3.7, 5.6, 8.3, 11.5, 10.6

Expand: `("a"+1/(2"a"))^2`

Expand : `(2"a"-1/"a")^2`

Expand : (a+b−c)²

Expand : (a−b+c)²

Expand : `(3"x"+1/(3"x"))^2`

Expand : `(2"x"-1/(2"x"))^2`

Find the square of `3"x"+2/"y"` 

Find the square of `"5a"/"6b"-"6b"/"5a"`

Find the square of `2"m"^2-2/3"n"^2`

Find the square of `5"x"+1/(5"x")`

Find the square of `8"x"+3/2"y"`

If  `"a"  +1/"a"=2`, find : `"a"^2+1/"a"^2`

If  `"a" +1/"a"=2`, find: `"a"^4+1/"a"^4`

If  `"m"  -1/"m"=5`, find : `"m"^2+1/"m"^2`

If  `"m"  -1/"m"=5`, find: `"m"^4+1/"m"^4`

If `"m"  -1/"m"=5`, find: `"m"^2-1/"m"^2`

If a² + b² = 41 and ab = 4, find : a + b

If `2"a"+1/(2"a")=8`, find : `4"a"^2+1/(4"a"^2)`

If `2"a"+1/(2"a")=8`, find : `16"a"^4+1/(16"a"^4)`
