Answer:
x>-1
Step-by-step explanation:
We will assume that here the question prompt us to solve the Inequality given and find the value of x for which is true and valid.
To begin with, let us re write our inequality clear as:
Eqn(1).
Now, since this is an Inequality it must be noted that <em><u>for any operation of multiplication/devision</u></em> with a<u> </u><u><em>Negative number</em></u>, the order of the Inequality will change from ≤ to ≥ and vice versa.
So having said that, let us solve Eqn(1) and obtain a value for as follow:
Remove Negative sign from both signs and change order of inequality from < to >.
Factor Out Bracket on Left Hand Side
Make Common Denominator on Both Sides
Eliminate denominator to simplify and remove fractions
Gather equal terms on each side
Simplify
Solve for
<em>Thus solving the inequality gives that x is greater than -1:</em>
<em> i.e. </em>
Hi there! The answer is x = 8.
Let's solve this equation step by step!
First we use the following rule.
which basically means that an exponential equation with the same base on both sides of the equation must also have the same exponents.
We get the following.
Now we use the following rule for logarithms.
When we apply this rule in our eqiation, we end up with the following.
Now we only need to do some basic math, work out the exponents first.
Subtract 8.
