Solution

Given,
$18 \times 81 = 1458$
Now, $81000 \times 180$
$= 81 \times 100 \times 18 \times 10 = 81 \times 18 \times 100 \times 10 [Associative property of multiplication] = 1458 \times 1000 = 1458000$
Hence , the required product is $1458000$

Study the pattern and answer the following:

$18 \times 1 = 18$

$18 \times 2 = 36$ (add $2$ tens and $2$ ones less than $18$ i.e. $[20 + 16]$ )

$18 \times 3 = 54$ (add $2$ tens and $2$ ones less than $36$ i.e. $[20 + 34]$ )

$18 \times 4 = 72$ (add $2$ tens and $2$ ones less than $54$ i.e. $[20 + 52]$ )

Now, continue this pattern
