Answer:
D)
Step-by-step explanation:
You have to use the laws of exponents to solve this:
Power of a Power: . In this case, , all of the numbers in the parenthesis need to be multiplied to the power of 3: .
Quotient of Powers: . In this case, , all of the exponents need to be subtracted (but the 4³ (64) and 8 need to be divided): .
Use the Power of a Power again for the expression at the right: . You get: . Keep the subtraction/negative sign where it is.
Together, you get: .

Answer:
12 is the answer.
Step-by-step explanation:
The best way to get the roots of the equation is to factorize the equation but when the factors are not possible then we should apply the quadratic equations formula to get the value of x.
Now we will try to factorize
x² - 8x -48 = 0
Now we multiply coefficient of highest degree term and constant term
48×1 = 48 which may be factored in 12×4. 8×6, 24×2.
Now we will choose 12×4 out of three because the 12-4 = 8 which is the coefficient of x.
Now its simple.
x²-12x + 4x -48 = 0
x(x -12) + 4(x-12) = 0
(x +4)(x-12) = 0
Therefore roots are x + 4 = 0
x = -4
and x - 12 = 0
x = 12
So the answer is 12.
