Q. Last ._”5^2 + 4^2 = (…)7^2 – 3^2 = (…)Gercep dapat : BA v:​

Jawaban:

5^2 + 4^2

( 5×5 ) + ( 4×4 )

25 + 16

= 41

7^2 – 3^2

( 7×7 ) – ( 3×3 )

49 – 9

= 40

Penjelasan dengan langkah-langkah:

= 5² + 4²

= ( 5 × 5 ) + ( 4 × 4 )

= 25 + 16

= 41

—

= 7² – 3²

= ( 7 × 7 ) – ( 3 × 3 )

= 49 – 9

= 40
