Answer:
A If y³ = 27, the value of y is 3. B If y³ = 64, the value of y is 4. C If y³ = 1, the value of y is 1
Step-by-step explanation:
Which statements are true? Mark all that apply. A If y³ = 27, the value of y is 3. B If y³ = 64, the value of y is 4. C If y³ = 1, the value of y is 1. D If y³ = 16, the value of y is 2.
Solution:
a) y³ = 27
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛27
y = 3
Option A is correct
b) y³ = 64
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛64
y = 4
Option B is correct
c) y³ = 1
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛1
y = 1
Option C is correct
d) y³ = 16
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛16
y = 2.52
Option D is wrong
