What is the solution to log (9x)-log 3 = 3?

xeze [42]

Answer:

The solution x = $\frac{e^{3} }{3}$

Step-by-step explanation:

Step 1:-

Given $log(9 x) -log 3 =3$

we have to use formula $log a-log b=log\frac{a}{b}$

$log(9 x)- log 3 = log(\frac{9 x}{3} )$ = $3$

Again by using formula $log a =b$

$a = e^{b}$

so $\frac{9 x}{3} =e^{3}$

step 2:-

$3 x = e^{3}$

$x = \frac{e^{3} }{3}$

The solution of given problem is $x=\frac{e^3}{3}$

beks73 [17]

Step-by-step explanation:

2(3x + 5y = -19)

What's 6 c ^ 2 + 2.5 D - D + 2C ^ 2 - 3D what is that simplified

adell [148]

I'm assuming that the lower case c and the upper case C are the same variables.

6C^2 + 2.5D - D + 2C^2 - 3D = 8C^2 - 1.5D
