Jika diketahui A= 2⁵⁰⁰⁰ + 2-⁵⁰⁰⁰ dan B= 2⁵⁰⁰⁰ - 2-⁵⁰⁰⁰ , maka nilai dari A² - B² adalah...

Plis dijawab

A² - B²

= (A + B)(A - B)

= ([2⁵⁰⁰⁰ + 2⁻⁵⁰⁰⁰] + [2⁵⁰⁰⁰ - 2⁻⁵⁰⁰⁰])([2⁵⁰⁰⁰ + 2⁻⁵⁰⁰⁰] - [2⁵⁰⁰⁰ - 2⁻⁵⁰⁰⁰])

= (2⁵⁰⁰⁰ + 2⁻⁵⁰⁰⁰ + 2⁵⁰⁰⁰ - 2⁻⁵⁰⁰⁰)(2⁵⁰⁰⁰ + 2⁻⁵⁰⁰⁰ - 2⁵⁰⁰⁰ + 2⁻⁵⁰⁰⁰)

= (2⁵⁰⁰⁰ + 2⁵⁰⁰⁰)(2⁻⁵⁰⁰⁰ + 2⁻⁵⁰⁰⁰)

= (2 × 2⁵⁰⁰⁰)(2 × 2⁻⁵⁰⁰⁰)

= (2⁵⁰⁰¹)(2⁻⁴⁹⁹⁹)

= 2²

= 4
