Answer:
Step-by-step explanation:
Since the denominator of each of those rational exponents is a 4, that means that the radical is a 4th root. The numerator of each exponent serves as the power on the given base. For example,
can be rewritten as
![\sqrt[5]{2^3}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B2%5E3%7D)
The little number that sits outside the radical, resting in the bend, is called the index. Our index is 4 (same as saying the 4th root). Put everything under the 4th root and let the numerator be the powers on each base:
![\sqrt[4]{6^1*b^3*c^1}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B6%5E1%2Ab%5E3%2Ac%5E1%7D)
which is written simpler as:
![\sqrt[4]{6b^3c}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B6b%5E3c%7D)
Answer:
45
Step-by-step explanation:
Evaluate 5 x^2 - 3 (x - 2) + x where x = 3:
5 x^2 - 3 (x - 2) + x = 5×3^2 - 3 (3 - 2) + 3
3^2 = 9:
5×9 - 3 (3 - 2) + 3
3 - 2 = 1:
5×9 - 3 + 3
5×9 = 45:
45 - 3 + 3
45 + 3 = 48:
48 - 3
| 4 | 8
- | | 3
| 4 | 5:
Answer: 45
Let the unknown number be x. Then (1/10)x = 0.002. To solve for x, multiply both sides by 1000 to remove the decimal fraction 0.002.
Then 1000(1/10)x = 1000(0.002), or 100x = 2. Dividing both sides by x returns
x=100/2, or x= 50 (answer)
