If a=2,b=3 and c=4,find the value of
3a-b+c
Substituting , a=2,b=3,c=4, we get ,
3a-b+c=3×2-3+4=6-3+4=3+4=7.
Hence , the value of the given expression is 7.
If 2160=2a.3b.5c, find a, b and c. Hence calculate the value of 3a×2−b×5−c
If a=4,b=0and c=-1, find the value of 2a3b+3b2c2-aca2+3ab.
If a=2,b=3,c=4, find the value of : 3a-b+2c
