Let's evaluate: $3\times 4^2$

ⓘ Calculate powers before multiplications, additions and subtractions. With a positive integer exponent, a power corresponds to a repeated product: $4^2$ = $4\times 4$ = $16$

$3\times 16$

ⅰ $3\times 16$ = $3\times (10+6)$ = $3\times 10+3\times 6$ = $30+18$ = $48$

▶Result:   $48$
