Which expression shows the simplified form of (8 r Superscript negative 5 Baseline) Superscript negative 3?

8 r Superscript 15
StartFraction 8 Over r Superscript 15 Baseline EndFraction
512 r Superscript 15
StartFraction r Superscript 15 Baseline Over 512 EndFraction

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

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
