Answer:
x^9/8
Step-by-step explanation:
The exponent property that you can use here is that when multiplying the two exponents, you add their exponents
Thus, (x^7/8) (x^1/4) = x^(7/8+1/4)=x^9/8
1+3x /4= 5/2
1+3x = 5*4/2
1+3x =10
3x =9
x = 3
20 % of the price: 0.2 · 840 = $168
The rest: $840 - $168 = $672
$372 : 6 = $112
The amount of each monthly payment will be $112.
Let's calculate the total cost per year:
6168 + 3280 + 2190 + 1200 = 12,838.
Four years will cost 12838 x 4 = 51,352
Your family will help you out with 17,600, so you will need to pay:
51352 - 17600 = 33,752
The pi root of 10,470 is approximately 321.457
