-7 is the value of discriminant for this equation.
Answer:
Step-by-step explanation:
The given expression has the first term n=1, so exponent = n-1 = 0
Similarly, for the second term n = 2, n-1 = 1
These exponents eliminate options 2 and 4.
Furthermore, the base is a fraction of 1/2, which applies to options 1 and 2 only.
The only viable option left that satisfies all conditions is option 1, which has exponents 0 and 1, with a base of (1/2).

Answer:
The number is 48
Step-by-step explanation:
First, let's call the number we are looking for n.
We can then write "two-thirds of the number" as 2/3n
We can also write "one-half of a number" as 1/2n
Finally, we are told 1/2n is the same as 2/3n −8 or: 1/2n = 23n −8
We can now solve for n: 1/2n − 2/3n = 2/3n −8 − 2/3n 1/2n − 2/3n = −8We next need to get the fractions over common denominators, in this case, 6 by multiplying each fraction by the necessary for of 1: (3/3) 1/2n − (2/2) 2/3n = −8 3/6n − 4/6n = −8 − 1/6n = −8.
We can finally solve for n by multiplying by -6 to isolate n −6 ⋅(−1/6)n = −8⋅ − 6
1n = 48
n =48
