in this, we can simply multiply by -2 at the bottom to get a -4g, and thus "eliminate" the g-variable
Answer:
D). (n + 4)^3/5.
Step-by-step explanation:
The fifth root is equal to exponent 1/5 and the n + 4 is taken to the power 3 so the answer is (n + 4)^3/5.
Answer: 2x^2 + 7x + 6
Step-by-step explanation:
You just add it up,
Because they aren’t the same power, you can’t add the x’s together.
Therefore they stay individual.
2x² + 7x + 6
