3000*(0.2)³-(-2)⁶

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

Step 1: Calculate 0.2 to the power of 3 0.2³ = 0.008

Step 2: Multiply the result from Step 1 by 3000 3000 * 0.008 = 24

Step 3: Calculate -2 to the power of 6 (-2)⁶ = 64

Step 4: Subtract the result from Step 3 from the result from Step 2 24 - 64 = -40

Therefore, the expression 3000*(0.2)³-(-2)⁶ is equal to -40.
