Answer:
3 to the power of 5 (I cant write as exponent)
Step-by-step explanation:
Answer:
86.9 cm^3
Step-by-step explanation:
You have to find the area of every face. Since the opposite sides have the same area, you can find three areas and then multiply by 2.
2(5.3x2)=21.2
2(4.5x2)=18
2(4.5x5.3)=47.7
You then add the values together...
21.2+18+47.7=86.9
Answer:
1260
Step-by-step explanation:
12/72 is 1/6 of the students going to the play
210 students go to play
210 times 6 is 1260
Step-by-step explanation:
here is the answer
the answer is 25.12
You can't have a negative number under a radical that has an even index. We have an even index since we are dealing with the square root. Because of that we have to get the imaginary i involved.

. Keeping that in mind, let's rewrite our problem:

. If -1 equals i-squared, we can sub that in. Also, since 8 = 4*2 and 4 is a perfect square, let's break that down at the same time:

. i-squared is a perfect square which can be pulled out as a single i, and 4 is a perfect square which can be pulled out as a 2. We will leave a 2 under the radical. Here's your simplification:

, choice C from above.
