x raise to 6/7

Step-by-step explanation:

since the base of both the numbers on the numerator is same,

4/7 + 3/7 = 7/7

so, x raise to 7/7

then since the base is same for the numerator and denominator,

7/7-1/7= 6/7

so x raise to 6/7

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
