Question

$21m ^{2} \div 7m$
​

Answer 1

Answer:

Anser is 3m

Step-by-step explanation:

21m² ÷ 7m = 21m²/ 7m

= 3m²/m

= 3m

( 2 power of m is in upper side and 1 power of m is in lower side so 1 power of upper side will be cancelled with the 1 power of Lower side and only 1 power on upper side is left)

Answer 2

Answer:

$21 {m}^{2} \div 7m \\ = \frac{21 {m}^{2} }{7m} \\ = \frac{3 \times \cancel7 \times \cancel{m} \times m}{ \cancel7 \times \cancel m} \\ = \underline{ \underline{3m}} \\ \\ Quotient = 3m \\ Remainder = 0$
