Step 1
The given equation is 0.4y4=2
The equation 0.4y4=2 can be solved as follows.
We multiply the decimal number by 10 to shift the decimal towards right hand side by one place.
Step 2
For clearing the decimals we multiply each term by 10.
10×0.4y10×4=10×2
4y40=20
Add both sides by 40.
4y40+40=20+40
4y=60
Divide both sides by 4.
4y4=604
 y=15
Therefore, y=15 is the solution of 0.4y4=2.
