You haven't stated the question. We'll assume that
what you're looking for is the value of the sum.
In preparation, we reflect:
Since 12 cows - 3 cows + 8 cows + 10 = 17 cows + 10,
12 sqrt(2) - 3 sqrt(2) + 8 sqrt(2) + 10 = 17 sqrt(2) + 10
If you need the actual numerical value, we go a step further:
17 sqrt(2) + 10 = 24.0416 + 10 = 34.0416(rounded)
0.6944
square it and cube it
The answer is 620. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.

If and only if you are working with a square, you get the square root of the number
0.6944
The square root of 64 is 8 and you can work it out using the square root algorithm.
Area of the rhombus: 0.5*7.5*10 = 37.5 square cm Perimeter using Pythagoras: 4*square root of (3.75^2 plus 5^2) = 25 cm
It is actually impossible to work out the square root of a shape but you can work out the square roots of the interior and exterior angles, the area and the perimiter
square it and cube it
(4/4)-(the square root of 4)-(the square root of 4)
The answer is 620. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.

It is -343 or 343
If and only if you are working with a square, you get the square root of the number
The square root of 372.5 = 19.3 rounded to 1 decimal place
