ANSWER

[tex]45+70-64[/tex]

EXPLANATION

We want to find the equivalent expression to:

[tex]3\cdot15+10(8-1)-8^2[/tex]

To do this, first simplify the bracket:

[tex]\begin{gathered} 3\cdot15+10(7)-8^2 \\ 3\cdot15+70-8^2^{} \end{gathered}[/tex]

Now, simplify the exponent:

[tex]3\cdot15+70-64[/tex]

Finally, simplify the muiltiplication:

[tex]45+70-64[/tex]

That is the answer.
