Question

the 10 = 2×2 and all can someone explain how they got that answer ​

Answer 1

Step-by-step explanation:

FIRST YOU NEED TO FIND LCM OF 180

AFTER THAT YOU HAVE TO WRITE IN THIS FORM LIKE THIS 2×2×3×3×5

SO NOW WE GOT IT'S LCM AND WE ARE ABLE TO SEE THAT BOTH 2 AND 3 HAVE THEIR PAIR OF 2 EXCEPT 5 SO IT IS A NOT A PERFECT SQUARE BUT IT CAN BE SQUARE IF IT HAVE PAIR OF 5 TO FOR EXAMPLE 400=2×2×2×2×5×5

HERE ALL NUMBERS ARE HAVING THEIR PAIR OF 2 THEREFORE IT IS A PERFECT SQUARE NUMBER
