Question

Verify that a + b is equal to |a|+|b|following value of a and b
1. A is equal to 7 by 3 b is equal to 2 by 3
2. Is equal to - 3 by 2 is equal to 3 by 4
3. A is equal to minus 1 by 8 equal to minus 3 by 5

Answer 1

Step-by-step explanation:

Anything which is in modulus,that is | | is always a positive value.

1.a=7/3,b=2/3

7/3+2/3=|7/3|+|2/3|

9/3=9/3

3=3

2.a=-3/2,b=3/4

-3/2+3/4=|-3/2|+|3/4|

-3/4=3/2+3/4

-3/4 is not equal to 9/4

3.a=-1/8,b-3/5

-1/8-3/5=|-1/8|+|-3/5|

-29/40 is not equal to 29/40

Hope it helped :)
