Question: Ramona wrote down an expression that was equivalent to... 3 . 15 + 10 (8 - 1) -82.(please look at the photo the numbers are different.)

Answer 1

`45+70-64`

Step-by-step explanation

We want to find the equivalent expression to:

`3\cdot15+10(8-1)-8^2`

To do this, first simplify the bracket:

`\begin{gathered} 3\cdot15+10(7)-8^2 \\ 3\cdot15+70-8^2^{} \end{gathered}`

Now, simplify the exponent:

`3\cdot15+70-64`

Finally, simplify the muiltiplication:

`45+70-64`

That is the answer.
