When the exponent blank is applied to a nonzero base, the result is always 1

When the exponent zero is applied to a nonzero base, the result is always 1 .

11

step-by-step explanation:

32.50-7.50=25

225/25=11

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
