Question

0,4 · (− 9)⁴​ + 1,6 · (− 9)³​ + 10.

Answer 1

0,4·(−9)⁴​+1,6·(−9)³​+10=0.4*9⁴+1.6*(-9³)+10=0.4*6561-1.6*9³+10=2624,4-1.6*9³+10=2634,4-1.6*729=2634,4-1166.4=1468

Answer 2

To calculate the expression, you need to follow the order of operations (PEMDAS/BODMAS):

1. Parentheses
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's solve the expression step by step:

1. First, we will calculate the exponents:

   • (−9)⁴ = (−9) × (−9) × (−9) × (−9) = 6561
   • (−9)³ = (−9) × (−9) × (−9) = -729

2. Next, we will perform the multiplications:

   • 0.4 × 6561 = 2624.4
   • 1.6 × (-729) = -1166.4

3. Finally, we add the results:

   • 2624.4 + (-1166.4) + 10 = 1458

So, the final result of the expression is 1458.
