  1. $\text{65 · [(1512 + 999) ÷ 3² – 45 · 4] + 65}$
    $\text{= 65 · [2511 ÷ 9 – 180] + 65}$
    $\text{= 65 · [279 – 180] + 65}$
    $\text{= 65 · 99 + 65}$
    $\text{= 6435 + 65}$
    $\text{= 6500}$
    $\text{Vậy 65 · [(1512 + 999) ÷ 3² – 45 · 4] + 65 = 6500}$

    65.[(1512+999) :3² – 45.4]+65
    = 65.[2511 : 9 – 45.4] + 65
    = 65.[279 – 180] + 65
    = 65.99 + 65
    = 6435 + 65
    = 6500
