Answer:
484
Explanation:
The little 2 in the top right corner is called a 'square', so for example 11² is reffered to as "eleven sqaured". What a 'square' does is demand the number it's denoting mupltiply by itself, so 11² (or "eleven squared") means 11x11.
That means 11²·2² is the same as (11x11)·(2x2).
11x11 is 121 and 2x2 is 4, so we can write this as 121·4
Note also that the dot here, '·', means multiply. (It is not a decimal point, decimals are placed at the bottom like this '.', whereas the multplication point is in the middle '·').
That means 121·4 is the same as 121x4, which is equal to 484.
