Question

0,8*(-1,25m)*(-2/5)*1/4а

Answer 1

0,8 · (-1,25m) · (-2/5) · 1/4а = (0,8·(-1,25))m · (-0,4·0,25)а = -1m · (-0,1)а = 0,1ma

Ответ: 0,1am.

Answer 2

To solve the expression, let's break it down step by step:

0.8 * (-1.25m) * (-2/5) * (1/4a)

Step 1: Multiply 0.8 by -1.25m: 0.8 * (-1.25m) = -1m

Step 2: Multiply the result from Step 1 by -2/5: -1m * (-2/5) = 2/5m

Step 3: Multiply the result from Step 2 by 1/4a: (2/5m) * (1/4a) = 2/20ma

Therefore, the simplified expression is 2/20ma.
