Vikentia [17]3 years ago
3 0

Answer:

The answer would be 10^2 or 100.

Step-by-step explanation:

If you take 10^3/10^5 x 10^4 and simplify it, you would get 1/10^ x 10^4. Then you reduce the expression to 10^2, or in alternate form, 100.

can a denominator be negative in literal equation? or should it be converted to positive, and change the numerator signs pls hel
Elis [28]

I don't think it really matters if the denominator is negative in a literal equation. Think about a simpler example with numbers. Does it matter whether a fraction is -1/2 or 1/-2? No, they are both the same. Therefore, I would say that the denominator of a literal equation can be negative.

Good luck with your exams!
