Estimate the following without actual calculation :

(i) 49 × 61

ANSWER⇩⇩

simplifying this⇨

$(7 \times 7) \times 61$

${7}^{2} \times {61}^{1}$

${\fbox{\pink {\underline{2989}}}}$

$\dag \purple{HOPE \: \: IT \: \: HELPS}\dag$

without actual calculation you just first simplify it into small numbers and then multiply them...
