Answer 1

y=2

Explanation:

Logarithmic Equations

The following equation is given:

`log_y 8+ log_y 4=5`

Recall the property:
`log_b x+lob_b y=log_b (x.y)`

Applying:
`log_y 32=5`

Now recall the definition of the log:

If:

`log_b a=x`

Then

`b^x=a`

The equation becomes:

`y ^5=32`

But 32=2^5, so:

`y ^5=2^5`

Equating the bases:

y=2
