Step-by-step explanation:

36

Step-by-step explanation:

A perfect square is a number that is the product of a whole number multiplied by itself.

This said, perfect squares when rooted will give a whole number.

Now, we can root each of these numbers and see which one gives a whole number.

√5=2.236

√8=2.828

√36=6

√44=6.633

As you can see, the only number that gives a whole number is 36, and therefore 36 is the only perfect square.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
