-6.927xx10^(-3)−6.927×10−3

Explanation:

First, you have to put both numbers with the same power, and do the calculation applying the distributive property:

9.23xx10^(-4)-7.85xx10^(-3)=0.923xx10^(-3)-7.85xx10^(-3)9.23×10−4−7.85×10−3=0.923×10−3−7.85×10−3

=(0.923-7.85)xx10^(-3)=-6.927xx10^(-3)=(0.923−7.85)×10−3=−6.927×10−3
