Answer:
 = 78
 = 78
 = 3.5
 = 3.5
Step-by-step explanation:
First we need to find  .
.
We can use the equation  to solve for
 to solve for  .
.
We can then change that equation to  , since the Commutative Property of Addition says that you can have any addition in any order.
, since the Commutative Property of Addition says that you can have any addition in any order.
Now, we can solve the equation.

Now that we solved  , we can now solve for
, we can now solve for  .
.
Since 25 equals  , we can solve the equation
, we can solve the equation  .
.
Here is how you solve it:

Since  equals 3.5, which is the simplest form, that is the answer.
 equals 3.5, which is the simplest form, that is the answer.

Step-by-step explanation:
= √2x × √8x³
= √(2.8x^4)
= √16x^4
= 4x²
 
        
             
        
        
        
We know, Force = mass × acceleration 
( i ) : 
Given, 
Force = 25 units 
Mass = 10 units 
Acceleration = ? 
Solution, 
Applying the formula of force, 
➡ Force = mass × Acceleration 
⏩ 25 = 10 × acceleration 
⏩ 25 / 10 =acceleration 
⏩ 2.5 units = acceleration 
( ii ) : 
Given, 
Force = 25 units 
Acceleration = 5 units
Mass =? 
Solution :
Applying formula, 
➡ Force = mass × acceleration 
⏩ 25 = 5 × mass 
⏩ 25 / 5 = mass
⏩ 5 units = mass
