Answer:
the fourth option: cannot be determined
Step-by-step explanation:
So the first option is the same as 21 times 9 which is more than 9, so it is incorrect.
The second option is the same as 2.3 times 21 and again its incorrect.
the third option
the fourth option has the same outcome because the fractions are equal.
therefore it cannot be determined
5x. 5x. 5x. 5x. 5x. 4x. 4x. 4x
Just seperate all of the numbers out. Because 5x is raised to the fifth it is being multiplied by itself 5 times, the same goes for 4.
My guess would be distributive. i maybe be wrong so don't get mad if I'm wrong.
Set up an equation
=
Solve.
