2*10+25*1225

To solve the expression \(2 \times 10 + 25 \times 1225\), we can break it down into two parts:

1. Calculate \(2 \times 10\): \[ 2 \times 10 = 20 \]

2. Calculate \(25 \times 1225\): \[ 25 \times 1225 = 30625 \]

Now, add the two results together: \[ 20 + 30625 = 30645 \]

Thus, \(2 \times 10 + 25 \times 1225 = 30645\).
