3.3^2 means 3.3 times itself 2 times or 3.3 times 3.3 or (use calculator)10.89
smaller powers (that's what 3.3^2 is, it means 3.3 to the second power) sometimes use different words to denote powers exg

x^2=x squared (square=2dimentionsl)
x^3=x cubed (cube=3 dimentionsl)
then x^4=x to the fourth, and so on
fifth, sixth, tecnth

tiny-mole [99]

Answer:

The first piece is 5 inches long, while the second is 15 inches and the third one is 20 inches.

Step-by-step explanation:

To determine the length of the 3 pieces, knowing that the total of the board is 40 inches, and that the second measures 3 times more than the first and the third measures 4 times more than the first, the following equation must be performed:

X + 3X + 4X = 40

8X = 40

X = 40/8

X = 5

Therefore, the first piece is 5 inches long, while the second is 15 inches and the third 20 inches.
