This may be wrong, but I think it is 4 days. Because after the first day, he’ll go 2 days before watering the first one, then 2 days later for both plants, because that would make 4 days and that’s how often he waters the second one.
- Find square root of 144 by factorisation method.
We can find the square root of 144 using the factorisation method. In this method, you need to factorise 144 first. Then, you'll get your answer in the form of prime factors. In this case, it's ⇨ 2 × 2 × 2 × 2 × 3 × 3.
__________________
To find the square root using factorisation, we need to group the same number in pairs. That is, 2 × 2 × 2 × 2 × 3 × 3 by grouping same numbers in pairs will become ⇨ (2, 2), (2, 2), (3, 3).

Now, you should take only 1 of the number from these groups. So, (2, 2), (2, 2), (3, 3) will change to ⇨ 2 × 2 × 3.

Finally, just multiply this set of numbers to find the square root of 144. 2 × 2 × 3 = 4 × 3 = ⇨ square root of 144.

- The square root of 144 is <em><u>12</u></em>.
X=2
So you solve for x by simplifying bath sides of the equation, then all you do is isolate the variables
12 x 2 = 24 ;
24 x 3 = 72 ;
72 x 4 = 288;
288 x 5 = 1440 ;

The answer is 1:4 because 55 - 11 = 44 so then you have 11 red and 44 green. Take the ratio 11:44 and simplify it to 1:4, and remember order matters. So you can't do 4:1.
