Which expression is equivalent to ^4 square root x^10
: /

Choice A is the correct answer. Nice work.

--------------

One way to see this is to use the rule

and that leads to

which means we'll divide the 10 and 4 to get 10/4 = 2.5 = 2 remainder 2

The "2 remainder 2" part is all we care about really. The whole part 2 forms the exponent over the first x shown in choice A, while the "remainder 2" portion is the exponent over the x inside the root.

Here's another example:

Note how 27/4 = 6 remainder 3. We see that the whole part 6 is the first exponent of the result while 3 is the second exponent.

the answer is 45 i just did it on oddesy ware

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
