So I have 4 math problems, whether you choose to answer them or not is your choice. Also thank you if you do answer them. :) But here they are.

#1 B^-2, solve for b=-3.

#2 (2t)^-4, solve for t=2.

#3 (m - 4)^-5, solve for m=6.

#4 2x^0y^-3, solve for x=7, and solve for y=-4.

The ^ means that there is a square root for that letter or number.

1) 9

2) 256

3) -32

4) -2744

Step-by-step explanation:

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.
