(−7c+8d)0.6 distributive property

Ksivusya [100]

We are given

$(-7c+8d)0.6$

we can use distribute property

Distributive property:

$(A+B)C=A*C+B*C$

so, we can write it as

$(-7c+8d)0.6=-7c*0.6+8d*0.6$

$(-7c+8d)0.6=-7*0.6c+8*0.6d$

now, we can multiply terms

and we get

$(-7c+8d)0.6=-4.2c+4.8d$ ..............Answer
