Keisha is solving the equation 7 to the power of x equals 9. which equation shows the first step she should take?

question 4 options:

log 7 to the power of x equals log 9

log 7 to the power of x equals 9

7 x equals log 9

log 7 to the power of x equals ln 9

mary is solving the equation 2 to the power of n end power minus 3 equals 83. her first three steps are shown:

step 1: 2 to the power of n end power minus 3 equals 83
step 2: 2 to the power of n equals 86
step 3: ln 2 to the power of n end power equals ln 86

which equation could be step 4?

question 5 options:
n equals ln 86 minus ln 2

ln 2 equals n ln 86

n plus ln 2 equals ln 86

n ln 2 equals ln 86

what is the exact solution of 2 e to the power of x equals 14?

question 6 options:

ln 7

ln 12

2 ln 14

2 ln 7

The correct answers are:

Question 4: the first step Keisha should take is: log to the power of x equals log 9.

Question 5: step 4 could be n ln 2 equals ln 86

Question 6: the exact solution is x=ln(7)

Step-by-step explanation:

Ok,

Question 4: the equation that shows the first step Keisha should take is:

(applying the properties of logarithms)

Solution: the first step Keisha should take is: log to the power of x equals log 9.

Question 5: Her first three steps are:

(adding 3 to both sides)

Solution: step 4 is: (applying the properties of logarithms)

Question 6: The exact solution of 2 e to the power of x equals 14 is:

(dividing both sides by 2)

(ln(e)=1)

Solution:

3, nah jk it's 2

step-by-step explanation:

it is 3 cause i'm sanic

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
