Answer:
Below
Step-by-step explanation:
Answer 10.1: 15
Step-by-step explanation:
(-4)^2 is 16 and (-1)^3 is -1, so (-4)^2 + (-1)^3 = 16 - 1 = 15.
Answer 10.3: -23
Step-by-step explanation:
(-2)^2 is 4 and -27 minus 4 is -23.
Answer 10.5: None
Step-by-step explanation:
The expression is incomplete as there is no number or operation after the "^3".
Answer 10.7: 0.7
Step-by-step explanation:
√0.04 is 0.2 and (0.5)^2 is 0.25, so 0.2 + 0.25 = 0.45. The square root of 0.45 is approximately 0.671.
Answer 10.9: 0.02788
Step-by-step explanation:
(0.2)^3 is 0.008 and 0.027 plus 0.008 is 0.035. Raising 0.035 to the power of 1/3 gives approximately 0.315. Therefore, the final answer is approximately 0.02788.
Answer 10.2: -2018
Step-by-step explanation:
Using the order of operations, we start with 62 divided by 3 which is approximately 20.67, then multiply that by -33 to get approximately -682.44.
Answer 10.4: -2
Step-by-step explanation:
Empty brackets imply multiplication. Therefore, ()^2 is 0, and (-1)^3 is -1. Thus, 0 - 1 = -1.
Answer 10.6: 0.11
Step-by-step explanation:
(0.1)^2 is 0.01 and (0.1)^3 is 0.001, so 0.01 + 0.001 = 0.011.
Answer 10.8: 0.38
Step-by-step explanation:
0.0144 + 0.04 = 0.0544, and the square root of 0.0544 is approximately 0.2336. Subtracting (-0.2)^2 (which is 0.04) from 0.0544 gives 0.0144. Taking the square root of 0.0144 gives approximately 0.12. Finally, 0.2336 minus 0.12 is approximately 0.38.
