There are no expressions inside parentheses (only numbers), so the order of operations tells us to work with exponents before anything else.
First, let's deal with the
#(-1)^3#
#(-1)^3 = (-1)times(-1)times(-1)#
#color(white)"XXXX" = 1 times (-1)#
#color(white)"XXXX" = -1#
So we now have:
#(1951 + (-1)1957)/3.00#
Now, multiply -1 by 1957 to get -1957.
#(1951-1957)/3.00#
Simplify the numerator by subtracting.
#(-6)/3.00#
And finally, simplify the fraction to get your answer.
#-2#
