Answer:
Roots (It has a solution)
Step-by-step explanation:
One method to find out whether or not this equation has a solution or not is to try to solve for x..
As we could find a solution, it has a root.
We can simplify the expression by using exponent properties, and we will see that the correct option is the fourth option.
<h3>How to simplify the expression?</h3>Remember the exponent property:
Here we have the expression:
We can reorder this to get:
The right side can be simplified to:
Now, we can move the decimal point one time to the left and increase the exponent by one, so we get:
Then we conclude that the correct option is the last one (where I rounded the expression to only 3 values after the decimal point).
