<h3>Answer:</h3>
An exponent represents repeated multiplication. For example, ...
... x^3 = x·x·x
... x^2 = x·x
If we divide these, the x's in the denominator cancel an equal number in the numerator:
... (x·x·x)/(x·x) = x
If we represent the repeated multiplication using exponents, we can represent the cancellation by subtraction:
... (x^3)/(x^2) = x^(3-2) = x^1 = x
Once we have this idea in mind that division can be done by subtracting denominator exponents, we can use it regardless of the magnitude or sign of the exponents involved.
Answer:
The answer to your question is:
16.- x = -6
17.- x = -4; x = 2
18.- x = -5
Step-by-step explanation:
16.-
x + 6 = 0(x - 4)
x + 6 = 0
x = - 6
17.-
(x + 4) (x - 2) = 0)(x + 6)
(x + 4)(x - 2) = 0
x + 4 = 0 x - 2 = 0
x = - 4 x = 2
18.-
2x + 10 = 0(3x - 12)
2x + 10 = 0
2x = - 10
x = - 10/2
x = -5
