We will substitute these in the formula of (a 2 b 2 c 2 ) a 2 b 2 c 2 = (a b c) 2 2 (ab bc ca) = (2 5 3) 2 2 (2×5 5×3 3×2) = 100 62 = 38 Answer (2 2 5 2 3 2) = 38 How To Use the (a 2 b 2 c 2 ) Formula Give Steps? Example 11 If a b c = 9 and ab bc ca = 40, find a 2 b 2 c 2 Solution We know that Example 12 If a 2 b 2 c 2 = 250 and ab bc ca = 3, find a b c Solution We know that Example 13 Write each of the following in expanded form (i) (2x 3y) 3 (ii) (3x – 2y) 3 Solution Example 14 If x y = 12 and xy = 27, find the value of x 3 y 3How do you solve word problems involving formulas? The Midpoints Of The Sides Ca And Ab Of A 8710 Abc Are D 3 4 E 8 9 And F 6 7 Respectively Find The Coordinates Of The Vertices Of The Triangle Mathematics Topperlearning Com Le8c5q (ab+bc+ca)^3 formula
