8 - 7x^2 + 3 = 4x^2 - 1
8+3-7x^2 = 4x^2-1
11-7x^2 = 4x^2-1
B. Commutative property of addition
We can swap numbers and obtain the same results.
In this case, we swapped 8+3 and added them.

2. (98)3
That is 98×98×98= 941192
For example. (1)3
That is 1×1×1= 1
Or (2)3
That is 2×2×2= 8. [ 2×2=4. ]. {4× 2 = 8 )
