Solving Exponential and Logarithmic Equation In exercise,solve for x or t.See example 5 and 6.

Virty [35]

Answer:

$x=\frac{6e^3}{e^3-1}$

Step-by-step explanation:

$ln x - ln(x - 6) = 3$

Apply natural log property

ln mn=ln m + ln(n), ln(m/n)=ln(m)-ln(n)

$ln x - ln(x - 6) = 3$

$ln(\frac{x}{x-6} )=3$

All natural log has base 'e'

$\frac{x}{x-6} =e^3$

cross multiply

$x=e^3(x-6)$

$x=e^3x-6e^3$

add 6e^3 on both sides and -x on both sides

$6e^3=e^3x-x$

$6e^3=x(e^3-1)$

Divide e^3-1 on both sides

$x=\frac{6e^3}{e^3-1}$

What is the value of x?

timurjin [86]

Step-by-step explanation:

${a}^{2} + {b}^{2} = {c}^{2}$

a^2 + 8^2 = 10^2

a^2 =10^2 - 8^2

a^2 =100-64

a^2 =36

(square root it)

a =6

Multiply the polynomials 3(x+7) (show work pls)

Evgen [1.6K]

Answer:

3x + 21

Step-by-step explanation:

(3)(x+7)

Now, we distribute the 3 in each term of (x+7)

So, 3*x = 3x and 3*7 = 21.

So our resulting term would be 3x+21.
