The product a, b, c of three rational numbers is negative, and is positive. Find the absolute value of a + the absolute value of b + the absolute value of c Value of The product a, b, c of three rational numbers is negative and the sum is positive. Find the absolute value of a + the absolute value of b + the absolute value of c Value of
Products a, b, c, their products are negative, and are positive,
Then only one negative number in a, b, c
Absolute value of a part + absolute value of b part + absolute value of c part
=1+1+(-1)
=1
