Without actually calclating cubes find value (4)3 + (-9)3 +(5)3 from math guides
Added by Leah D.
Step 1
First, we can use the formula for the sum of cubes: a³ + b³ + c³ = (a + b + c)(a² + b² + c² - ab - ac - bc) Using this formula with a = 4, b = -9, and c = 5, we get: 4³ + (-9)³ + 5³ = (4 - 9 + 5)(4² + (-9)² + 5² - 4(-9) - 4(5) + (-9)(5)) Simplifying the Show more…
