Given: 3^(x − 4) = 6
To find: Solution to the given expression using change of base formula
Answer: The given expression is 3^(x − 4) = 6 Taking log on both sides, we get - log(3^(x − 4)) = log6
(x - 4) log3 = log6
x - 4 = log6/ log3
x - 4 = (∵ change of base formula)
x - 4 = 1.631
x = 5.631
Thus x = 5.631 is the answer in the nearest thousandth.
We are given : In a furniture rental store a down payment = $100.
Monthly charge of the table = $72.50 per month.
Total amount to be paid for the table = $535.
Let us assume number of months be n for which Hilde rented the table.
We are given equation also 72.50n + 100 = 535.
We need to solve the equation for n.
72.50n + 100 = 535.
<em>Subtracting 100 from both sides, we get </em>
72.50n + 100-100 = 535-100
72.50n = 435
<em>Dividing both sides by 72.50, we get </em>
72.50n/72.50 = 435/72.50
n = 6.
<h3>Therefore, for 6 months Hilde rented the table.</h3>
