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
