Answer:
6^20
Step-by-step explanation:
When two indices are in brackets, you just have to multiply them.
Y/x = 5 bc in order to isolate the variables you must divide by x on both sides to separate the 5, leaving you with y/x=5
-10x+4.
5x-7x is -2.
-2x-8x is -10x.
you cannot simplify the 4
alternatively, you could write -10x+4 as
-2(5x-2)
