Question

a+b+c=45;a+b=23;a+c=25
1. then the value of (a)^2×(b)^2×(c)^2 = ________
2.then √(a)^2+(b)^2 is equal to (a+b) true/false {if false what is the answer }
​

Answer 1

Answer:

Step-by-step explanation:

GIVEN ;

A+B+C=45

A+B=23

A+C=25

FIND A^2*B^2*C^2

AS WE KNOW THAT

(A+B+C)^2=A^2+B^2+C^2+2(AB+BC+CA)

(45)^2=(A+B)^2+(A+C)^2+2(AB+BC+CA)

A+B=23

(A+B)^2=23^2=  529

(A+C)^2=25^2 =625

45^2=625+529+2*(AB+BC+CA)

2025=1154+2*(AB+BC+CA)

871/2=(AB^2 * BC^2 * CA^2)

(a)^2×(b)^2×(c)^2=436   (ROUND OF)
