Question:-
$\frac{81 \times 81 - 15 \times 15}{81 - 15}$
​

Answer 1

Step-by-step explanation:

Step-by-step explanation: IDENTITY :

Step-by-step explanation: IDENTITY :(A²-B²) = (A+B)(A-B) HERE; A = 82. B = 18. THEREFORE;

Step-by-step explanation: IDENTITY :(A²-B²) = (A+B)(A-B) HERE; A = 82. B = 18. THEREFORE;82²-18²= (82+18)(82-18) = 100*64. = 6400. THEREFORE ;

Step-by-step explanation: IDENTITY :(A²-B²) = (A+B)(A-B) HERE; A = 82. B = 18. THEREFORE;82²-18²= (82+18)(82-18) = 100*64. = 6400. THEREFORE ;82²-18²=6,400. HOPE THIS HELPS.

Answer 2

Answer:

photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
