$170
Step-by-step explanation:
15 percent of 200 is 30 and 30 minus 200 would be 170
The law is the Inverse law of Addition/Multiplication
4/3-7/9

= 15/27
= 5/9 which is C
its 4
because u divied
9z
4th root of z = z^1/4
=> 3 * z^1/4
=> 3z^1/4
3z^1/4 * 3z^3/4
=> 3 x 3 x z^1/4 + 3/4
=> 9z^4/4
=> 9z^1
=> 9z
