Question

Find the least number by which 9 1875 should be multiplied to get a perfect square

Answer 1

Answer:

11

Step-by-step explanation:

91875 have a factors by prime factorization:

i.e. 5×5×5×5×3×3×11

for doing square root we should have the factors in pairs

therefore, in

$5 \times 5 \times 5 \times 5 \times 3 \times 3 \times 11$

we have pairs

1. 5×5
2. 5×5
3. 3×3 then now 11 prime number has no pair now for making given number perfect square we have to multiply the 91875 with 11
