The two numbers in each column have to add to 23
So under 7 you write 16, above 4 you write 19, etc
The rule will say x + y = 23
Step-by-step explanation:
according to BODMAS
5×5^2÷5-6
5^2=25
5×25÷5-6
5×5-6
25-6=19

Step-by-step explanation:
Answer:
The square root of 160 is between 12 and 13 because 12x12=144 but 13x13=169. 160 is on between these so it must be between 12 and 13.
40 is a square root of 1600 because the equation looks like this:
40x40 It has 2 zeros, so the answer also has 2 zeros. Hence why it is 1600 not 160.
The answer is: "123454321"
