Question

Find out the smallest number by which 162 must be multiplied to get a perfect square also find out the square root of the perfect square so obtained

Answer 1

Answer:

√162=√(2×3×3×3×3)

√162=√2×(3×3)×(3×3)

√162=√2×3×3

as we can't make pair of 2, we should multiply 162 by 2

162×2=324

√324=√(2*2)*(3*3)*(3*3)

√324=2*3*3

√324=18 ans

Answer 2

Answer:

it should be multiplied by 2 to get a perfect square

Step-by-step explanation:

162\2

81\3

27\3

9\3

162 =2*3*3*3*3

there is pair of (3,3) (3,3) but 2 is left so it should be multiplied by 2

square root:- 162*2 = 324

√324 =18
