3000•(0.2)³-(-2)⁶

To simplify the expression, let's break it down into smaller steps:

Step 1: Calculate (0.2)³ To find (0.2)³, we simply multiply 0.2 by itself three times: (0.2)³ = 0.2 * 0.2 * 0.2 = 0.008

Step 2: Calculate (-2)⁶ To find (-2)⁶, we multiply -2 by itself six times: (-2)⁶ = -2 * -2 * -2 * -2 * -2 * -2 = -64

Step 3: Multiply 3000 by the results from Step 1 and Step 2 Now we can substitute the calculated values back into the original expression: 3000 * (0.008) * (-64)

Step 4: Calculate the final answer To get the final answer, we multiply 3000 by 0.008 and then multiply that result by -64: 3000 * 0.008 * -64 = -15.36

Therefore, the result of the expression 3000 • (0.2)³ - (-2)⁶ is -15.36.
