Jawaban:

• 89(2) × 5² + 7
• = ( 89 + 89 ) × 5² + 7
• = 178 × 5² + 7
• = 178 × ( 5 + 5 + 5 + 5 + 5 ) + 7
• = 178 × ( 10 + 5 + 5 + 5 ) + 7
• = 178 × ( 15 + 5 + 5 ) + 7
• = 178 × ( 20 + 5 ) + 7
• = 178 × 25 + 7
• = 4.450 + 7
• = [tex]\bf\color{ff968a}{{{4.457}}}[/tex]

Penyelesaian:

89(2)×5²+7

=178×25+7

=(178×25)+7

=4.450+7

=4.457
