Answer:
Step-by-step explanation:
VW = 9
VX is the whole line
VW and WX makes up VX so:
VW + WX = VW, or:
(4x - 7) + (3x) = (5x + 1); add 3x
7x - 7 = 5x + 1; subtract 5x
2x - 7 = 1; add 7
2x = 8; divide 2
x = 4
Now Put 4 in for VW:
(4(4)-7); multiply
(16-7)
9
Given:

To find:
The exponential form of given equation.
Solution:
We have,

According to the property of the logarithm,

Using the above property of the logarithm, we get
Therefore, the required equation in exponential form is
.
12$ Cuz 6X2+=12........................................
