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.
