Answer:
$5504
Step-by-step explanation:
Given that :
Principal amount = $500
Interest = 4% simple interest annually
Amount added at the end of each year :
First year:
Principal + (Principal * rate * time)
500 + (500 * 0.04) = 520
$520 + $250 = $770
2nd year:
770 + (770 * 0.04) = $800.80
$800.80 + $250 = 1050.80
3rd year:
1050.8 + (1050.8 * 4) = 5254
$5254 + 250 = $5504
(81m^6)^1/2 = (3^4*1/2) (m^6*1/2) = 3²m³
1/27
1/27
125
Step-by-step explanation:
Given that,
a - b = 3
9^(1/2b) /3^a = 3^(2/2b) /3^a
= 3^b/3^a
= 3^(b-a)
= 3^(-3)
= 27^(-1)
= 1/27
27^(1/3b) /9^(1/2a) = 3^(3/3b) /3^(2/2a)
= 3^b/3^a
= 3^(b-a)
= 3^(-3)
= 27^(-1)
= 1/27
125^(1/3a) /25^(1/2b) = 5^(3/3a) /5^(2/2b)
= 5^a/5^b
= 5^(a- b)
= 5^3
= 125
