Answer:
Step-by-step explanation:
You need to find two numbers that are perfect square (I'm not really sure), and these numbers should be near in the number 78
Two numbers: 8 and 9
8 × 8 = 64
9 × 9 = 81
64 78 81
(8) (9)
Then you will find the perfect square by trying to multiply the number between 8 and 9, like this:
8.1 × 8.1
8.2 × 8.2
8.3 × 8.3
8.4 × 8.4
8.5 × 8.5
8.6 × 8.6
8.7 × 8.7
8.8 × 8.8
8.9 × 8.9
So the answer is 8.8.
Ps. Hope that this will help you although its wrong grammar.
