Answer:
Add 2 to each side
x=1/2
Step-by-step explanation:
(3√8x - 2 )= 4
Add 2 to each side
(3√8x - 2 +2= 4+2
3√8x = 6
Divide each side by 3
3/3√8x = 6/3
√8x = 2
Square each side
(√8x)^2 = 2^2
8x = 4
Divide each side by8
8x/8 = 4/8
x = 1/2
Working out the expression 7(3ˣ) is first to calculate the value of 3ˣ then multiply the answer to 7.
For example, let x = 2
Then 7(3ˣ) = 7(3²) = 7 × 9 = 63
With the same value of x = 2, calculating 21ˣ = 21² = 441, which isn't the same answer with the expression 7(3ˣ)
Remember that the formula for the difference of squares is 
, where 
and 
are expressions or values.
In this case, we have two expressions, 
and 
. We are also given that their difference of squares is 4444. Using the formula, we can say:
Now, we can solve for :
We now know that the first number is 1110. To find the second number, we must add 2 to the first number, which means that the second number, represented by , is equal to 1112.
Our two numbers are 1110 and 1112.
each one gets 2 and their will be 4 slices left
