5^-3 is 1/125
The negative in the exponent makes it so there is a 1 over the problem if there was no negative. When you have a negative in the exponent, the answer will be the reciprocal (opposite) of the question with no negative.
For example,
9^2 = 81
9^-2 = 1/81
The hypotenuse is always the longest side of a triangle and seeing that it is 8, X has to be something smaller so X is likely 4.
Answer:
60
Step-by-step explanation:
4 times 3 = 12 12 times 5 =60
Answer:
The Volume, Area, and Surface Area can be found with division and multiplication. Like so: (1st question, start) = 12m divided by 6m which equals 2. That is the answer for the first one.
Step-by-step explanation:
Multiplication for finding Volume, and Division for finding Area, and Surface Area.

Step-by-step explanation:
(2 decimal places)
If you want to arrange the tiles into a square, you will need 3.46 in each row/column.
This is physically impossible, hence you round it down to 3.
(If you round it up, you won't have enough tiles since
)
Thus, the square area will be ![3*3=9](https://tex.z-dn.net/?f=3%2A3%3D9)
Tiles left: ![12-9=3](https://tex.z-dn.net/?f=12-9%3D3)
