1.Evaluate

a.(243/32)^-0.4​

4/9

Step-by-step explanation:

negative exponent means 1/...

so, this is

(32/243)^(4/10) = (32/243)^(2/5)

that means to the power of 2 and then pulling the 5th root.

so, let's pull the 5th root first, and then we square

(32/243)^(2/5) = (2⁵/3⁵)^(2/5) = (2/3)^2 = 4/9

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

10000

step-by-step explanation: divide by 2,
