Answer:
Step-by-step explanation:
Expanded form is the method to find the place value of any digits. In this question, we need to write the number in expanded form. The given number is, N = 39,005
Here, 3 is in ten thousand place, 9 is in thousand place and 5 is in unit place. Its expanded form is given by :
So, the given number thirty nine thousand and five can be written as as expanded form. Hence, this is the required solution.
Step-by-step explanation:
x^3 is a perfect cube, 8 is a perfect cube, so we use difference of cubes.
Cube root of x^3 is x.
Cube root of 8 is 2
So
a=x
b= 2.
Set these equations equal to zero
If we do the discriminant, we get a negative answer so we would have two imaginary solutions,
Thus the only real root is 2.
If you want imaginary solutions, apply the quadratic formula.
