Answer:

Both answer shown

IF it is

$e^{ln 7x}= 7x$

IF it is

$e^{ln 7}\times 1}=7$

Step-by-step explanation:

Given: Little confusion is in the question

e^ln7 x1

i.e $e^{ln 7x}$

To Find:

$e^{ln 7x}= ?$

Solution:

We know Logarithmic identity as

$\ln e = 1$

$\ln e^{x} = x$

Similarly,

$e^{\ln x}=x$

IF it is

$e^{ln 7x}= 7x$

IF it is

$e^{ln 7}\times 1}=7\times 1=7$

Answer:

Probability [Randomly choose plant Juan's mother want] = 3 / 5

Step-by-step explanation:

Given:

Total number of plant in store = 30 plants

Number of plant kind Juan's mother want = 18

Find:

Probability [Randomly choose plant Juan's mother want]

Computation:

Probability of an event = Number of favorable outcome / Total number of outcomes

Probability [Randomly choose plant Juan's mother want] = Number of plant kind Juan's mother want / Total number of plant in store

Probability [Randomly choose plant Juan's mother want] = 18 / 30

Probability [Randomly choose plant Juan's mother want] = 3 / 5
