Step-by-step explanation:

Just substitute the values of a and b

2a^2 + 3b^3 - 10

2x2^2 + 3 x (-2)^3 - 10

= 2 x 4 + 3 x (-8) - 10

= 8 - 24 - 10

= 8 - 34

= -26

Answer:

- 26

Step-by-step explanation:

Given

2a² + 3b³ - 10 ← substitute a = 2, b = - 2 into the expression

= 2(2)² + 3(- 2)³ - 10

= 2(4) + 3(- 8) - 10

= 8 - 24 - 10

= - 16 - 10

= - 26
