Question

(-1,2p³q)(10p²r²)=
Help me

Answer 1

For this case we have the following expression:
 $(-1.2p^3q)(10p^2r^2)$
 When making multiplication, the first thing you should keep in mind is the following property:
 Same basis, the exponents are added.
 We have then:
 $-12p^{3+2}r^2q$
 Rewriting we have:
 $-12p^{5}r^2q$
 Answer:
 The simplified expression is given by:
 $-12p^{5}r^2q$
