-2,7•(-10)²+131

To solve the expression \(-2.7 \cdot (-10)^2 + 131\), follow these steps:

1. Calculate \((-10)^2\): \[ (-10)^2 = 100 \]

2. Multiply \(-2.7\) by \(100\): \[ -2.7 \cdot 100 = -270 \]

3. Add \(131\) to \(-270\): \[ -270 + 131 = -139 \]

Thus, the final result is: \[ \boxed{-139} \]
