Solution equation: x = 1 + X / 2 + 2 / 4 + X / 8 + X / 16

Solution equation: x = 1 + X / 2 + 2 / 4 + X / 8 + X / 16

x=4.8

38: x = 19 / 4: 9 / 8 (solve the equation, write the process.)

0.38:x=19/4:9/8
According to the fact that the product of two external terms is equal to the product of two internal terms, the
0.38*9/8=19x/4
Multiply both sides by eight at the same time, and you get
0.38*9=38x
Divide both sides by 38 to get
0.01*9=x
Namely
x=0.09

16^3 * 4^5=2^x

16^3 * 4^5=2^x
(2^4)^3 *(2^2)^5=2^x
2^12 *2^10=2^x
2^22=2^x
x=22

16/3:2/5=16/7:× x=?

16/3:2/5=16/7:×
x=2/5x16/7÷16/3
x=6/35
