Question

please answer it i cant answer it​

Answer 1

Step-by-step explanation:

bohot asaan hai be.

agar tere ko nai ATa matlab tune formulas Yaad nai kiye hai..

Commutative = 7x 4x = 4x 7x

Associative = 8 + ( 5 + 12 )

Distributive = ( 6 × 5 ) + ( 6 × 9 )

Multiplicative Inverse = 7 + ( 1 × 1 ) = 7

Dekhle

Formula of commutative = a + b = b + a

example, 2 + 3 = 3 + 2( ✓✓✓ )

exception = 2 - 3 = 3 -2 ( ×× )

Formula of associative = ( a + b ) + c = a + ( b + c )

example, ( 2 + 3 ) + 4 = 2 + ( 3 + 4 )

[ ✓✓✓ ]

exception = ( 2 - 3 ) - 4 = 2 - ( 3 - 4 ) [ ×× ]

Formula of Distributive = a × ( b + c ) = a×b + a×c

or a(b + c) = ab + ac

example, 2( 3 + 4 ) = 2×3 + 2×4 = 6 + 8 = 14

Answer 2

Answer:

7×4=4×7

(8+5)+12=8+(5+12)

6×(5+9)=(6×5)+(6×9)

69+111=69+111

7+(0×1)=7

I hope this helps you.
