Answer:
x^8-x^6+x^3-5
Step-by-step explanation:
The top exponent goes before
=8x + (-3) (5) + (-3) (9x)
=8x + -15 + -27x
=8x + -15 + -27x
(8x + -27x) + (-15)
19x +-15
19x -15
Answer: 5 and 1/3
Step-by-step explanation: To add mixed numbers, first add the fractions.
So here, we have 2/3 + 2/3 which is 4/3.
Then add the whole numbers.
So we have 2 + 2 which is 4.
So our answer is 4 and 4/3.
But notice, that since 4/3 is an improper fraction, or answer is not in lowest terms. 4/3 can be rewritten as the mixed number 1 and 1/3. So 4 and 4/3 is the same as 4 + 1 and 1/3 which is 5 and 1/3.
Since 5 and 1/3 is in lowest terms, this is our final answer.
So we can say that 2 and 2/3 + 2 and 2/3 is 5 and 1/3
