Your question seems to be incorrect.
Given a + b = 10 and a^2 + b^2 = 58.
We know that a^3 + b^3 = (a + b)(a^2 - ab + b^2)
= > (10)(58 - ab) -------- (1)
---------------------------------------------------------------------------------------------------------------
We know that (a + b)^2 = (a^2 + b^2 + 2ab)
= > (10)^2 = (58 + 2ab)
= > 100 = 58 + 2ab
= > 42 = 2ab
= > ab = 21. ----- (2)
-----------------------------------------------------------------------------------------------------------------
Substitute (2) in (1), we get
= > a^3 + b^3 = (10)(58 - 21)
= (10)(37)
= 370.
Therefore, a^3 + b^3 = 370.
Hope this helps!
