Q (+35)

Jawab:

16

Penjelasan dengan langkah-langkah:

Bilangan Berpangkat

begin{aligned}left({4}^{2}times{8}^{-2}right)^{-2}&=left(4^2right)^{-2}:times:left(8^{-2}right)^{-2}\&=4^{2times(-2)}:times:8^{-2times(-2)}\&=4^{-4}:times:8^{4}\&=4^{-4}:times:left(4times2right)^{4}\&=4^{-4}:times:4^4:times:2^4\&=4^{-4+4}times:2^4\&=4^{0}times:2^4\&=1times:2^4\&=2^4\&=bf16\end{aligned}

therefore boxed{ {Bigl.}left({4}^{2}times{8}^{-2}right)^{-2} = bf16 }

PERPANGKATAN ADALAH SUATU BENTUK OPERASI MATEMATIKA YG PENGERJAAN NYA BERULANG-ULANG ATAU DISEBUT JUGA PERKALIAN GANDA

SOAL :

1) ( 4² × 8² )²

= ( 2 × 2)²

= 2 ( 4 6 )²

= ( 2² )²

= 2 [ 2 × 2 ]

= 2

= [ 2.2.2.2 ]

= [ 4 . 2 . 2 ]

= [ 8 . 2 ]

= 16
