For this case we must find an expression equivalent to:

By definition of power properties we have to:

So, rewriting the expression we have:


By definition of multiplication of powers of the same base, we put the same base and add the exponents:

Answer:
Option B
<span>4 4/8 + 3/4
=4 1/2 + 3/4
=4 2/4 + 3/4
= 5 1/4</span>
If your teacher do not put the value of the q all the letters will be 1 so: 1+5=6 (after you just simplify)
3/4 or 0.75 or just 75%. doesn't get much simpler
