If you write 1xrt9 with spaces and brackets, you get:

1 x rt(9).

I believe this is most likely to mean

1 multiplied by the square root of 9,

which is more usually written on here as:

1 * sqrt(9).

7 x 4 = 28

sqrt(9) = 3

1 * sqrt(9) = 3

Adding 28 and 3 gives 31.

That’s correct.

any ideas???
