2. (3 points) Calculate
(1) $96 \times 15 \div(45 \times 16)=$ $\qquad$ .
(2) $(\underbrace{125 \times 125 \times \cdots \times 125}_{100 \uparrow 125}) \times(\underbrace{8 \times 8 \times 8 \times \cdots \times 8}_{101 \uparrow 8})=$ $\qquad$
(3) $2+4+6+8+\cdots+100=$ $\qquad$ .
【Solution】Solution: (1) $96 \times 15 \div(45 \times 16)$,
$$
\begin{array}{l}
=\frac{96 \times 15}{45 \times 16}, \\
=2 ;
\end{array}
$$

The answer is: 2.
$$
\begin{aligned}
\text { (2) } & \{100 \text { } 125\} \times\{101 \text { } 8\} \\
= & (125 \times 8) \times(125 \times 8) \times \cdots \times(125 \times 8) \times 8, \\
= & 100 \uparrow 1000 \times 8, \\
= & 80 \cdots 0(300 \text { } 0) .
\end{aligned}
$$

The answer is: $80 \cdots 0(300$ 0$)$.
$$
\begin{aligned}
& \text { (3) } 2+4+6+8+\cdots+100, \\
= & (2+98)+(4+96)+\cdots+100+50, \\
= & 100 \times 25+50, \\
= & 2550 .
\end{aligned}
$$

The answer is: 2550.
