Question

If a =_70,b=4 and c=_10,verify a×(b×c)=(a×b)×c

Answer 1

$a = 70,b = 4 \: and \: c = 10, verify \\ rule - - > a \times (b \times c) = (a \times b) \times c \\ \\ ans. \: \: a \times (b \times c) = (a \times b) \times c \\ \\ now \: put \: the \: value \:o f a,b \: and \: c\: \\ \\ 70 \times (4 \times 10) = (70 \times 4) \times 10 \\ 70 \times 40 = 280 \times 10 \\ 2800 = 2800 \\ LHS = RHS \\( left \: hand \: side ) =( right \: hand \: side) - - \geqslant verified.$
