Answer 1

QUESTION:- Find the value of the following algebraic expression when p = 1 q = 2 and r =0 b. 15p² - 2r³ + pqr - 18q - 5r²q.

ANSWER:

$\sf15 {p}^{2} - 2r^{3} + pqr - 18q - 5r ^{2} q$

$\sf \: Putting \: values \: p = 1, \: q = 2 \: and \: r= 0$

$\sf \: 15(1)^{2} - 2(0)^{3} + (1)(2)(0) - 18(2) - 5(1) ^{2}(2)$

$\sf15 - 0 + 0 - 36 - 10$

$\sf \: 15 - 46$

$\sf \: - 31$
