So for the first one, you would have to multiply 2 six times. and then 2 with a -4 exponent is a little challenging. Okay, you would have to make it a fraction. so it would be 1/16. then you would just multiply 2 seven times.
Answer:
C
Step-by-step explanation:
If x is the average (arithmetic mean) of m and 9, y is the average of 2m and 15, and z is the average of 3m and 18,
x=(m+9)/2
y=(2m+15)/2
z=(3m+18)/2
the average of x, y, and z
=(x+y+z)/3
=(m+9+2m+15+3m+18)/3
=(6m+42)/3
=2m+14
ans is C
Let's find the equivalent expressions ~
