Can someone explain why
(-5k^2m)(2km)^4(3km^4)^2
——————————————
k^2m^3
Simplifies to -720k^6m^10

But 3m/m^4 simplifies to 3/m^2
Even though their both fractions how come only one stays a fraction? What’s the difference so I can figure out in the future?

1. = -720

2. = (or 3)

Step-by-step explanation:

1. The given expression is:

With respect to the principle of exponential, we have;

 =

 Applying the law of indices,              

=

=

= -720 x

= -720

= -720

2.

divide the numerator and denominator with common factor m,

=

This can not be simplified further since there are no more common factors, so that;

= (or 3)

answer is : muchas/tipicas

have a nice day!

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
