Subtract. write your answer in simplest form. 5^3/4 - 2^11/12

a. 4
b. 3^3/4
c. 2^5/6
d. 2^7/12

Here, As the exponent and base both are different, we can't simply it by using any mathematical rule, so we have to convert them into decimal then comparing with options.

So, 5^3/4 + 2^11/12

= 3.34 - 1.88

= 1.46

Which is most precise to 2^7/12 = 1.49

In short, Your Answer would be: Option D

Hope this helps!
