I'm not completely sure but this is what I would do.
evaluate <span>(1/ 4)^x - 1 </span>as is. But change the (1 /2)^2x to (2/4)^2x. This way both fractions have the same denominator and in this sense, the same base. The 2/4 base still evaluates into 1/2 so nothing, mathematically, is being broken here.

Answer:
x= 0 ,
, 
Step-by-step explanation:
Given, equation is
+
=
. →→→ (1)
Now, by cubing the equation on both sides, we get
(
+
)³ = (
)³
⇒ (15x-1) + (13x+1) + 3×
×
(
+
) = 64 x.
⇒ 28x + 3×
×
(
) = 64x.
(since from (1),
+
=
)
⇒ 12×
×
(
)= 36x.
⇒ 3x =
.
Now, once again cubing on both sides, we get
(3x)³ = (
)³.
⇒ 27x³ = (15x-1)(13x+1)(x).
⇒ 27x³ = 195x³ + 2x² - x
⇒ 168x³ + 2x² - x = 0
⇒ x(168x² + 2x -1) = 0
⇒ by, solving the equation we get ,
x = 0 ; x =
; x = 
therefore, solution is x= 0 ,

Answer:
Each Novis share 7 sheep and each Expert share 12 sheep.
Step-by-step explanation:
Here, N represent the number of novices and E represent the number of experts needed for the company to meet its goal,
∵ All novices share the same number of sheep per day and all experts share the same number of sheep per day.
Let the sheep per day by a Novice = x and sheep per day by an expert = y,
So, the total sheep = xN + yE
According to the question,
Total sheep ≥ 700
⇒ xN + yE ≥ 700,
By here, we have given the inequality for the given scenario,
7N+12E ≥ 700
By comparing,
x = 7 and y = 12
Hence, Each Novis share 7 sheep and each Expert share 12 sheep.
