Answer: Greater than 3 but less than 17
Step-by-step explanation: To find the smallest possible side, subtract the largest of the given sides by the smallest. To find the largest possibly side, you add both given sides. In this case, you would subtract 7 from 10 to find the smallest side, which would be 3, and add both sides to find the largest possible side of 17.
160 = 2 x 2 x 2 x 2 x 2 x 5 = 2^5 x 5
243 = 3 x 3 x 3 x 3 x 3 = 3^5
So
(160 * 243)^1/5
= 5th root of (160 * 243)
= 5th root of (2^5 * 5 * 3^5)
= 2 * 3 * (5th root of 5)
= 6 * (5th root of 5)
Answer is D. 6 * (5th root of 5)
Answer:
100
Step-by-step explanation:
She wants to average 85, so adding ALL three of her scores, divided by 3 needs to equal 85.
(75 + 80 + x)/3 = 85
Times by 3.
75 + 80 + x = 255
155 + x = 255
subtract 155.
x = 100
She needs 100 on the third test.
The cube root of -27 is -3
3√-27 = -3
You can check this by plugging your answer back it
X= -3
-3^3 = -27
