Answer:
9
Step-by-step explanation:
1) Using n√a^m = (n√a)^m, rewrite the root like (3√27)^2
2) Write the number in exponential form with a base of 3: (3√3^3)^2
3) Calculate the cube root: 3^2
4) Evaluate the power: 3^2=9
Answer:
<h2>10.7%</h2>
Step-by-step explanation:
Step one:
given
expected weight= 28pounds
Actual weight= 25 pound
Required:
percent error

δ= percent error
vA =actual value observed
vE =expected value
δ=25-28/28*100
δ=-3/28*100
δ=0.107*100
δ=10.7%
The percent error is 10.7%
