23 Calculer chacun des nombres suivants: A=[(-2)³+(-1)⁷]² -[(-2)²+(-2)³]²
B=(-2)⁰+(-2)¹ +(-2)³+(-2)⁴ +(-2)⁵
C=(19 – 3²)³ x 7,45 X(-93,5)⁰(2³x5³)²​

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

a≈380.13mi² would be your answer if the radius was 11 miles
