Question

8 is subtracted from three times the product of numbers p, q and r. Express the above statement as an algebraic expression.

• A. $3pqr-8$
• B. $3pqr+8$
• C. $8-3pqr$
• D. $3pq+q-8$

Answer 1

The correct option is A $3pqr-8$

Product of the numbers p, q and r can be written as $p\times q\times r$.
This can be also written as $pqr$.
Three times the product of numbers p, q and r can be written as $3pqr$.
Given, 8 is subtrated from this product.
Therefore, subtraction of 8 from three times the product of numbers p, q and r can be written as ${}^{\prime }3pqr-8^{\prime }$.
