−27

−9

9

27

When the exponent is negative, you need to move it to the other side of the fraction to make the exponent positive.

For example:

or  

 or  

    Move to the other side of the fraction to make the exponent positive

 or (1 - 2)(3³)

(1 - 2)27    Simplify what's in the parentheses

(-1)27

-27     Your answer is the 1st option

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
