2. 4² × 3² = 144

penyelesaian

________________________

[tex] \frac{33}{14} \times 21 + 1 = [/tex]

[tex] (\frac{33}{14} \times \frac{21}{1} ) + \frac{1}{1} [/tex]

[tex] = \frac{33}{14} \times \frac{21}{1} [/tex]

[tex] = \frac{33 \times 21}{14 \times 1} [/tex]

[tex] = \frac{693}{14} + \frac{1}{1} [/tex]

[tex] = \frac{693}{14} + \frac{14}{14} [/tex]

[tex] = \frac{707 \div 7}{14 \div 7} [/tex]

[tex] = \frac{101}{2} [/tex]

[tex] = 50 \frac{1}{2} [/tex]

=========================

[tex]4 {}^{2} × 3 {}^{2} = [/tex]

[tex] =( 4 \times 4) \times (3 \times 3)[/tex]

[tex] = 16 \times 9[/tex]

[tex] = 144[/tex]

Penjelasan dengan langkah-langkah:

~ 33/14 × 21 + 1

= 33/2 × 3 + 1

= 99/2 + 1

= (1 + 49) 1/2

= 50 ½

__

~ 4² × 3²

= (4 × 4) × (3 × 3)

= 16 × 9

= 144
