What is the lcm of 8x2y2 and 10x2y3? a.40x2y3 b.40x4y5 c.80x2y3 d.80x4y6

The multiples of 8 are: 0, 8, 16, 24, 32, 40, 48, ...

The multiples of 10 are: 0, 10, 20, 30, 40, 50, ...

LCM(8, 10) = 40

LCM(x²y², x²y³) = x²y³

Therefore

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
