The product of the sum of two perfect cubes:
a³ + b³ = (a + b)(a² - ab + b²)
The product of the difference of two perfect cubes:
a³ - b³ = (a - b)(a² + ab + b²)
----------------------------------------------------------------------------------------------------------------
Remember to follow FOIL:
(b^2 + 8)(b^2 - 8)
(b^2)(b^2) = b^4
(b^2)(-8) = -8b^2
(8)(b^2) = 8b^2
(8)(-8) = -64
b^4 - 8b^2 + 8b^2 - 64
Combine like terms:
b^4 (-8b^2 + 8b^2) - 64
b^4 - 64
b^4 - 64 is your answer

For a pear, it would be 3/16 of a chance. For an orange, it would be 1/4 of a chance.
Answer:
We cannot find the 3rd Side unless & until the perimeter of triangle is not given!
If he maintained a steady speed, he would drive 3 kilometers far after 3 hours.
<h3>What is steady speed?</h3>
Uniform or steady speed refers to a body's motion in a given direction without acceleration.
Since steady speed means a constant speed in changing time intervals, we would consider he speed as 1 km/h.
Time for which he is maintaining the steady speed is 3 h.
We know by the formula, Distance = Speed × Time
Therefore, putting the values given we get
Distance = 1 × 3 kilometers
Hence, distance travelled by he after 3 hours of maintaining steady speed is 3 kilometers.
