Answer:
○ x³\⁷
Step-by-step explanation:
Since you are multiplying ⁷√x three times, you write it like this first, ⁷√x³, then according to one of the Six Exponential Rules, ⁿ√aᵐ = aᵐ\ⁿ, ⁷√x³ gets rewritten as x³\⁷.

Answer:
C, Plus or minus 3
Step-by-step explanation:
to solve 3x² - 27 = 0, we want to get the x by itself, so lets add 27 to both sides.
3x² = 27 < divide both sides by 3 to get x alone
3x²/2 =x²
27/3 = 9
x² = 9 < we can use the square-root property and square both sides of the equation to get x alone. we use the ± because there are 2 possible solutions to a square rooted number
√x² = x
√9 = 3
x = ±3
looking at our answer choices, the correct answer is C
The answer is x = 6 1/2♣♣♣ if your trying to solve <span>7(x - 2) = 3(x + 4</span>
