D) 3+x/10+x > 8/10!

the second part is a

Step-by-step explanation:

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
