Tolong bantu kak beserta cara dan konsepnya

Jawab:

P = $25^{2009} + 25^{-2009}$

Q= $25^{2009} - 25^{-2009}$

tentukan hasil P² – Q²

P² – Q² = (P+Q)(P-Q)

P² – Q² =( $25^{2009} + 25^{-2009}$ + $25^{2009} - 25^{-2009}$ )( $25^{2009} + 25^{-2009}$ -( $25^{2009} - 25^{-2009}$ ))

P² – Q² =( $25^{2009}$ + $25^{2009}$ ) ( $25^{-2009}$ + $25^{-2009}$ )

P² – Q² =(2 ( $25^{2009}$ )) (2( $25^{-2009}$ ))

P² – Q² = 4 ( $25^{2009}$ )( $25^{-2009}$ )

P² – Q² = 4 ( $25^{2009}$ )( $frac{1}{25^{2009} }$ )

P² – Q² = 4 x 1

P² – Q² = 4

semoga membantu, jadikan jawaban terbaik yaa^^

P = 25²⁰⁰⁹ + 25-²⁰⁰⁹

P = 25²⁰⁰⁹-²⁰⁰⁹

P = 25

Q = 25²⁰⁰⁹- 25-²⁰⁰⁹

Q = 25²⁰⁰⁹/-²⁰⁰9

Q = 25-¹

Q = 1/25

P²-Q²

25² – (1/25)²

625 – (1/625)

625 – 625-¹

625-¹ / 1/625
