Can you simplify this? this is an urgent one!?

Question

Square root 1125x^4 is what simplified.

Answer 1

15 * sqrt(5) * x^2

Answer 2

sqrt(1,125x^4) (first take the square root of x^4, which is simply x^2)

x^2*sqrt1,125 (now find the largest perfect square factor of 1,125, which is 225 and goes into 1,125 five times)

x^2 * sqrt225 * sqrt5 (take the square root of 225 and multiply it to the coefficient)

15x^2*sqrt5 <===ANSWER

Answer 3

sq rt (25*9*5 x^2 x^2)

5*3 x ^2 sq rt 5

15x^2 sq rt 5

some times it helps to work with smaller numbers.  You know that 25 goes into 1125.  It goes in 45 times.  9*5=45 and 9 is 3^2
