Answer 1

Answer:

5 is the smallest number to be divided from 1620 to make it as a perfect square

Step-by-step explanation:

1620 = (2x3x3)² x 5

1620/5 = 18²

324 =18²

Answer 2

$\huge\sf\pink{Answer}$

☞ 5 Should be divided and the square root of the number is 18

$\rule{110}1$

$\huge\sf\blue{Given}$

✭ 1620 has to be divided by a number to make it a perfect square

$\rule{110}1$

$\huge\sf\gray{To \:Find}$

◈ The Number?

◈ The square root of the number obtained?

$\rule{110}1$

$\huge\sf\purple{Steps}$

So here we shall first find the factors of the given number,

➳ $\sf 1620 = 2 \times 2 \times 5\times 3\times3\times3\times3$

So here when we pair each factor into squares

$\quad$◕ 2²

$\quad$◕ 3²×3²

$\quad$◕ 5

So here as 5 doesn't have a pair that is the number that has to be divided,that is

➢ $\sf \dfrac{1620}{5}$

➢ $\sf \red{324}$

Finding its square root,

➝ $\sf \sqrt{324}$

➝ $\sf\orange{18}$

$\rule{170}3$
