Question

2,5 в минус 1 степень умножить на 4 =?

Answer 1

${2.5}^{ - 1} \times 4 = \frac{1}{2.5} \times 4 = \frac{8}{5} = 1 \frac{1}{3}$

Answer 2

To calculate $2.5^{-1}$ (2.5 raised to the power of -1) and then multiply the result by 4, follow these steps:

Step 1: Calculate $2.5^{-1}$: $2.5^{-1} = \frac{1}{2.5} = 0.4$

Step 2: Multiply the result by 4: $0.4 \times 4 = 1.6$

So, $2.5^{-1}$ multiplied by 4 is equal to 1.6.
