29²+35²+33²+31²-34²-32²-30²-28²=?
1 Answer
Explanation:
- In order to solve this question, we must first consider the value of each of the square numbers. This is done in the following way:
#(29*29)+(35*35)+(33*33)+(31*31)-(34*34)-(32*32)-(30*30)-(28*28)# - We then carry out the multiplication to solve each for each multiplication. This is done in the following way:
#(841)+(1225)+(1089)+(961)-(1156)-(1024)-(900)-(784)# - We then carry out the addition and subtraction:
#(841)+(1225)+(1089)+(961)-(1156)-(1024)-(900)-(784)=252#
