Question

How do I find 2a^2 + 3b^3 - 10 for a = 2 and b = -2

Answer 1

`-26`

Step-by-step explanation

We want to find the value of the expression:

`2a^2+3b^3-10`

for the value of:

`a=2;b=-2`

To do this, substitute the given values of a = 2 and b = -2 into the expression:

`\begin{gathered} 2(2)^2+3(-2)^3-10 \\ 8-24-10 \\ \Rightarrow-26 \end{gathered}`

That is the answer.
