Question 1(i)
Write the following numbers in the expanded form:
(i) 2,79,404

Answer 1

(i) 2,79,404 = $2,00,000+70,000+9,000+400+00+4$
$=2\times 100000+7\times 10000+9\times 1000+4\times 100+0\times 10+4\times 1$
$=2\times {10}^5+7\times {10}^4+9\times {10}^3+4\times {10}^2+0\times {10}^1+4\times {10}^0$
