What common base can be used to rewrite each side of the equation 2^x+3-3=5
1 answer:
The common base that can be used to rewrite each side of the equation is 2.
<h3>How to find the common base used to rewrite each equation?</h3>The common base that can be used to rewrite each side of the equation is as follows:
2ˣ⁺³ - 3 = 5
add 3 to both sides
2ˣ⁺³ - 3 + 3 = 5 + 3
2ˣ⁺³ = 8
Hence,
2ˣ⁺³ = 2³
Therefore, the common base that can be used to rewrite each side of the equation is 2.

Answer:
The difference of two numbers using identity is 4.
Step-by-step explanation:
Given: The sum of the numbers is 12 and the difference of the squares of the numbers is 48.
To find the difference of two numbers using identity
Let the two numbers be a and b, then
Given that the sum of the numbers is 12
that is a + b = 12 .........(1)
Also, given the difference of the squares of the numbers is 48.
that is ..........(2)
Using given identity
We have
Substitute the known values, we have,
Divide both side 12 , we have,
Thus, the difference of two numbers using identity is 4.
13+4x=1-x
4x=-12-x (minus 13 from each side)
5x=-12 (add x to each side)
You divide -12 by 5x
-12÷5x=2
⇒2.4
x=2.4
4x=-12-x (minus 13 from each side)
5x=-12 (add x to each side)
You divide -12 by 5x
-12÷5x=2
x=2.4
