Answer:
4.02 x 10 x 10 x 10 x 10 x 10 
Step-by-step explanation:
The part that needs expanding is the exponent. Since it is to the power of 5 there needs to be 5 written out 10's, all multiplied. 
4.02 x 10 x 10 x 10 x 10 x 10 
 
        
                    
             
        
        
        
Answer:
y = x [1- ]
]
Step-by-step explanation:
If the variable x represents the employee's pay before tax-exempt expenses and taxes are removed and y variable represents the employee's take-home pay after these deductions and if fifteen percent of an employee's taxable income is collected each paycheck, then y is given by
y = x [1- ]. (Answer)
]. (Answer)
For, example, an employee's payment is deducted by $350 at the rate of 15% tax and other deduction.
Therefore,  , ⇒ x = $2333.33 is the before tax income of the person.
, ⇒ x = $2333.33 is the before tax income of the person.
