Simplify the following completely, show all work.

4 + ✓-27

4+3i

Step-by-step explanation:

the needs to be simplified

first, I broke it down to and

simplifies to i ;and  can be broken down to and

can be simplified further to 3

Now all you have to do is put it together

4(which you didnt have to do anything to)+ 3i( 3 from the sqrt of 9 and i from the sqrt of -1) sqrt 3( which cant be simplified further)

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
