I’m not sure but here’s a method that might help: write out the numbers least to greatest, the dots each represent one number, then remember that you add and divide for the mean( add up all the numbers then divide them by how many dots there are) and for median it’s the middle number, if there’s two in the middle add them and divide it by 2
Answer:
2308.5
Step-by-step explanation:
Multiply and divide by 2
Answer:
do you have any pictures?
Step-by-step explanation:
From my research, the question is actually looking for the radical equivalent of 27^(2/3). Let us solve this below:
27^(2/3) = [cube root (27)]^2 = 3^2 = 9
Therefore, the final answer to the expression is 9.
You can use F.O.I.L. for this, which if you don't know stands for first outer inner last, so multiply the first in each parentheses, then the outer, then the inner, then the last. yours would be 3*5+3*√7+(-√7)*5+(-√7)*√7 => 15+3√7-5√7-7 => 8-2√7
Final answer:
8-2√7
Hope I could help :)
