An estimate for ^3 is
A. 1
B. 1.2
C. 1.7
D. 2
How do I find the answer? Help please?
0^3 = 0
Thanks and I got C? Can you help me with one more An estimate for -�ã93 is?
A. -8.1
B. -8.5
C. -9.1
D. -9.5
1.2^2 = 1.44
1.7^2 = 2.89
2^2 = 4
So, C looks good.
81 = 9^2
100 = 10^2
93 is kind of in the middle, so what is midway between 9 and 10?
To find an estimate for ^3, you can follow these steps:
1. Start by taking the square root of the given number. In this case, ^3 means cubed, so we need to find the square root of the number to estimate.
2. For the given options A to D, calculate the square root of each option. To do this, you can use a calculator or basic math operations.
3. Compare the square roots you calculated with the options given. Determine which option's square root is closest to the number you calculated in step 1.
4. Select the option that has the closest square root to your calculated value. That option will provide you with a good estimate for ^3.
In this particular example, we're looking for an estimate for ^3. Let's calculate the square root of each option to find out the closest estimate.
A. The square root of 1 is 1.
B. The square root of 1.2 is approximately 1.095.
C. The square root of 1.7 is approximately 1.303.
D. The square root of 2 is approximately 1.414.
By comparing these square roots, we can see that option D has the closest square root to the number we calculated in step 1. Therefore, the estimate for ^3 is 2, which is option D.
