Answer:
r = 4
Step-by-step explanation:
z ^ (7/10) * z^ ( 33/10)
We know that a^ b* a^c = a^(b+c)
z^ (7/10 +33/10)
z^ (40/10)
z^4
r = 4
2(x + y) + 3(x + y)
first distribute:
(multiply 2 into everything in the first parenthesis, and 3 into everything in the second)
2x + 2y + 3x + 3y
Second simplify (add all like terms (adding in this case) )
(2x + 3x) + (2y +3y)
5x + 5y
your answer is: 5x + 5y
