Question

Find the additive inverse of the multiplicative inverse of the expression (-3 ) x (-10) 5

Answer 1

Solving the expression :
-3 × -10 × 5
= 150

Additive inverse :
→(-150)
It simply means change the signs to opposite. If its + change to - and vice-versa :)

Multiplicative inverse :
→ 1/150
It means that you have to find out the reciprocal of the number. In simple words, interchange the places of numerators and denominators.

Answer 2

-3 × -10 × 5
= 150 
so.. the additive inverse of 150 is -150 ...
and multiplicative inverse of 150 is 1/150...
