Question

Find the value of each expression b= 9 and a = 1/3.expression: b^2 - 9a

Answer 1

We are given the following expression

`b^2-9a`

Where the values of a and b are also given

a = 1/3

b = 9

Let us substitute these values into the given expression and then simplify the expression

`\begin{gathered} b^2-9a \\ (9)^2-9((1)/(3)) \\ (9*9)-(9)/(3) \\ 81-3 \\ 78 \end{gathered}`

Therefore, the expression is simplified to 78
