Which of the following is equivalent to 2 ln e^ln 5x = 2 ln 15?

neonofarm [45]

Answer:

x = 3

Step-by-step explanation:

Given in the question an equation,

$2lne^{ln5x}=2ln15$

Step 1

$e^{lnx}=x$

so,

$2ln(5x)=2ln15$

Step 2

cancel 2 on both sides of the equation

$ln{5x}=ln15$

Step 3

$ln{5x}-ln15=0$

$ln\frac{5x}{15}=0$

Step 4

$ln\frac{x}{3}=0$

Step 5

$e^{ln\frac{x}{3}}=e^{0}$

Step 6

x/3 = 1

x = 3(1)

x = 3

30 - -5n + 16 + 3n =

MatroZZZ [7]

Answer:

8n + 46

Step-by-step explanation:

Combine like terms. First, simplify the signs. two negatives directly next to each other equals one positive:

- (-5n) = + 5n

30 + 5n + 16 + 3n = (30 + 16) + (5n + 3n)

(30 + 16) = 46

(5n + 3n) = 8n

8n + 46 is your answer.
