Answer:
12
Step-by-step explanation:
We have,
Let the large number is =x
Square of smaller number is =8x
Now, According to given question,
x
2
−8x=180
⇒x
2
−8x−180=0
⇒x
2
−(18−10)x−180=0
⇒x
2
−18x+10x−180=0
⇒x(x−18)+10(x−18)=0
⇒(x−18)(x+10)=0
⇒x−18=0,x+10=0
⇒x=18,x=−10
⇒x=−10,18
Either
x=−10 and x=18
x=18 is true (Positive value)
Now, square of small number
=18x=18×8=144
144
=12
Hence, this is the answer.

Solution ==》
☆ Given =》
The difference of square of two natural numbers is 180.
Square of smaller no is 8 time the number
☆ To find =》
Two numbers
☆ Explanation =》
Let the larger no is =x
Square of smaller number =8x
According to question
x²-8x=180
x²-8x-180=0
x²-(18-10)x-180=0
x²-18x+10x-180=0
x(x-18)+10(x-18)=0
(x-18)(x+10)=0
x-18=0, x+10=0
x=18, x= -10( neglected)
x= 18
Two numbers are 18 and 8×18=144
