Difference between (-7)2 and -(7)2
Rules of algebra to remember – Square of every number (negative or positive) is always positive.
Negative sign multiplied to a positive number makes the number negative
SOLUTION
(-7)2 = -7×-7 = 49
and
-(7)2 = -(7×7) = -49
Difference between (-7)2 and -(7)2 = 49 - (-49) = 49 + 49 = 98
If we take it otherwise, difference between -(7)2 and (-7)2 = -49 - 49 = -98
These are the two possibilities as mentioned above.
