Answer:
a = 2
b = 5
Step-by-step explanation:
Given :
(ar^b)^4 = 16r^20 ; a and b are positive integers :
Opening the bracket :
a^4r^4b = 16r^20
a^4 = 16 - - - - - (1)
r^4b = r^20 - - - (2)
a^4 = 16
Take the 4th root of both sides :
(a^4)^(1/4) = 16^1/4
a = 2
From (2)
r^4b = r^20
4b = 20
Divide both sides by 4
4b/4 = 20/4
b = 5
Hence ;
a = 2
b = 5
The least common denominator of 6/7, 3/5, and 1/4 is D. 140
The LCD of 3/5 and 1/4 is 20. However, 6/7 must be considered.
So, 20 x 7 = 140.
140 ÷ 7 = 20
140 ÷ 5 = 28
140 ÷ 4 = 35
Least common denominator is need when we add or subtract fractions.
As you move from each place to the left one place, the value increases by 10. If you move right a place, the value decreases by 10.
