What is the smallest positive integer n such that the square root on 126n is an integer?

I will brainliest!

It should be 14. All it's saying is what's the lowest whole number (without a decimal place) can multiply 126, and be square rooted to make another number without a decimal place. 14 does just that if you plug it in for n. Every other number under 14 gives you a number with a decimal place.

sqrt (126•n) is what the question looks like without the words.

The answer is 14 ...
