Answer:
The answers should be A, E, and F.
Step-by-step explanation:
The rule for multiplying the same bases, but with different exponents, goes like this. Lets say you have four to the 5th power, and four to the 7th power. When you multiply them, the base will stay as four, but you will ADD the exponents! So, the answer to this would be four to the 12th power. This rule can even be applied when one, or even <em>both</em> of the exponents are negative! However, keep in mind that this can only be done when the base integers are the SAME.
-8x - 2y = -4
When y = -5x
-8x - 2(-5x) = -4
- 8x + 10x = -4
2x = -4
x = -4/2 = -2

The value of z after solving the equation z³ = 8 is 2.
<h3>Define cube root.</h3>
The result of a number (x) being multiplied three times is referred to as the cube of that number. The phrase "cube root" in mathematics means "the number that needs to be multiplied three times in order to acquire the original number." Let's now examine the cube root formula, in which y is equal to the cube root of x. ∛x = y. Any integer can be represented as the cube root by the radical sign ∛, which has a little 3 written on the top left of the sign. Writing 1/3 as a number's exponent is another method to represent a cube root.
The given equation
z³ = 8
The number 8 can be written as
8 = 2 × 2 × 2
= 2³
So,
z³ = 2³
So, comparing both sides, we get
z = 2
This is the solution to the equation.
