What is the sum of StartRoot 3 EndRoot – i and 2 – StartRoot 3 EndRooti? (2 + StartRoot 3 EndRoot) – (1 –StartRoot 3 EndRoot )i
(2 + StartRoot 3 EndRoot) – (1 + StartRoot 3 EndRoot)i
(2 + StartRoot 3 EndRoot) + (1 + StartRoot 3 EndRoot)i
(2 + StartRoot 3 EndRoot) + (1 – StartRoot 3 EndRoot)i

10

step-by-step explanation:

7+3=10

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
