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)
