Question

39. Express (21)^2 as the sum of two consecutive natural number.​

Answer 1

Answer:

220+221

Step-by-step explanation:

21^2=441

Divide 441 by 2 to get a number around which the numbers would lie

441/2=220.5

220.5+0.5=221

220.5-0.5=220

Hence, the two numbers are 220 and 221

Answer 2

21^2=441
441/2-.5 & 441/2+.5
220 & 221
