Question

1)(-16*14,5)*2,9 2) -0,5*(-14)*12,5*0,6

Answer 1

1.(-16*14,5)*2,9=-232*2,9=-672,8

2.-0,5*(-14)*12,5*0,6=7*12,5*0,6=87,5*0,6=52,5

Answer 2

Let's solve the expressions step by step:

1. (-16 * 14.5) * 2.9

First, calculate the value inside the parentheses: -16 * 14.5 = -232

Now, multiply this result by 2.9: -232 * 2.9 = -672.8

So, the value of the first expression is -672.8.

2. -0.5 * (-14) * 12.5 * 0.6

First, calculate the value inside the parentheses: -0.5 * (-14) = 7

Next, multiply this result by 12.5: 7 * 12.5 = 87.5

Finally, multiply the result by 0.6: 87.5 * 0.6 = 52.5

So, the value of the second expression is 52.5.
