The value of the square root of 82 is between which two integers?

1 answer:

8 0

The answer: 9 and 10 or 8 and 9
8x8=64
9x9=81
10x10=100
They are close by 18 so If it’s only an answer I would go for 8 and 9

Associative property of addition changing the grouping of add once does not change the sum. The option 3 illustrates the associative property of addition. Thus this is the correct option.

<h3>Given-</h3>

The options are given in which the associative property of the addition has to be found.

<h3>Associative property </h3>

Associative property of addition is the changing the grouping of add once does not change the sum.

Option 1-

$(3+19)-12=(3+12)-19$

In the above option with changing the bracket the sign of 19 and 12 is changed. This will affect the result of the addition. Hence, option 1 is incorrect.

Option 2-

$3+(19-12)=3+(19+12)$

In this case, the sign changed. Thus the result of the sum will be different. Hence the option 2 is incorrect.

Options 3-

$(3+19)-12=3+(19-12)$

In this case, brackets are changed but the sign is not changed. Thus the result will be the same. Hence, option 3 illustrates the associative property of addition. Thus this is the correct option.
