30  

Step-by-step explanation:

Each digit in a whole number has a place value, based on its position from the decimal point.

The place value of a digit increases by a factor of 10 as we move left on the place value chart and decreases by a factor of 10 as we move right.  

Numbers to the left of the decimal point increase in place value in the order: ones, tens, hundreds, etc.

The value of a digit is the digit multiplied by its place value.

So, the digit 3 in 731.8 has a value of 30.

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5
