Question

Express the following as an algebraic expression:​
(iv) The product of $12,x,y,z$ minus the product of $5,m\text{and}n$.

Answer 1

$\text{Product of}12,x,y,z=12\times x\times y\times z$

$=12xyz........\left(i\right)$

$\text{Product of}5,m,n=5\times m\times n=5mn.......\left(ii\right)$
Subtracting (ii) from (i), we get

$\therefore$ $12xyz-5mn$

Hence, the required expression is $12xyz-5mn$.
