Question

0,2•(-3)³-0,1•(-3)²-3

Answer 1

0,2•(-3)³-0,1•(-3)²-3=0,2 * (-27) - 0,1 * 9 - 3 = -5,4  - 0,9 - 3 = - 9,3

Answer 2

Let's simplify the expression step by step:

1. Start with the first term: 0.2 * (-3)³

   • (-3)³ is equal to -27 because -3 raised to the power of 3 is -27.
   • Now, multiply -27 by 0.2: 0.2 * (-27) = -5.4

2. Move to the second term: 0.1 * (-3)²

   • (-3)² is equal to 9 because -3 squared is 9.
   • Now, multiply 9 by 0.1: 0.1 * 9 = 0.9

3. Finally, subtract 3 from the result obtained in step 1:

   • -5.4 - 0.9 = -6.3

So, the value of the expression 0.2 * (-3)³ - 0.1 * (-3)² - 3 is -6.3.
