This reduces nicely if you first notice that 16/81 = (2/3)^4.
Then use the properties of powers (of positive real numbers):
(16/81)^(3/4) = ((2/3)^4)^(3/4) = (2/3)^3 = 8/27
Download photomath it really helps and solves the question for you and shows you the steps
The equation of a line is defined by: y=mx+b
Step 1: Find the slope (rise over run) so, the rise is 15.7 and the run is 6. 15.7/6=2.62
y=2.62x+b
Step 2: Find the b value (y intercept) - this is where the line goes through the y axis. In this case, it's 15.7
Step 3: add the slope and the b value together - y=2.62x+15.7
