Step-by-step explanation:
Answer:
729 in³
Step-by-step explanation:
Fill in the given numbers in the formula and solve for V.
... A = 6V^(2/3) . . . . . . the given formula
... 486 = 6V^(2/3) . . . . with the given area filled in
... 81 = V^(2/3) . . . . . . . divide by 6
... 81^(3/2) = V . . . . . . . raise to the 3/2 power. (2/3)·(3/2) = 1, so we have V on the right
... 729 = V . . . . in³
_____
You may have noticed that (81 in²)^(3/2) becomes 729 in³. The exponent operations work on the units, too.
Answer:
(ab+a-b+1)(ab-a+b+1)
Step-by-step explanation:
- (1 - a²) (1 - b²) + 4ab=
- 1 -a²-b² +a²b² +4ab =
- (a²b² +2ab +1 )- (a²-2ab+b²)=
- (ab+1)² - (a-b)²=
- (ab+1 +a-b)(ab+1 -a+b)=
- (ab+a-b+1)(ab-a+b+1)
