6.22222222222
2 over 3 to the power of 2 + 5 × 2 − 4=6.22222222222
We know that we can do
ab+ac=a(b+c)
so find common factor
factor them
27a=a times 3 times 3 times 3
21=3 times 7
common factor=3
3=a
27a/3=9a
21/3=7
so now we have
(3)9a+(3)7=3(9a+7)
160.67 = 2000*8*r
So 160.67 = 16000r
Then divide 16000 on both sides 160.67/16000 =r/16000
0.01=r
