Question

8^2+(10-3)-2x(4+3)=




(6+5-2)x3-8^2:(9-5)+(4+3)x(8-5)=




2x3^3-30:6+√100-64=

Answer 1

8² + (10-3) -2 . (4 + 3 ) = 
64 + 7 - 2 . 7 = 
64 + 7 - 14 = 
71 - 14 = 
57 

(6 + 5 -2) . 3 - 8² : (9-5) + (4 + 3) . (8-5)=
9 . 3 - 64 : 4 + 7 . 3 = 
27 - 16 + 21 =
11 + 21 = 
32


2 . 3³ - 30 : 6 +√100 - 64 = 
2 . 27 - 5 + 10 - 64 = 
54 - 5 + 10 - 64 = 
49 + 10 - 64 =
59 - 64 = 
- 5
