Answer:
Linette paide $14.45 and Sheila paid $12.84 in total that is $27.29.
Step-by-step explanation:
The 20th term is -106
15,9,3,-3,-9,-15,-21,-28,-35,-41,-46 (10) -6 x 10 = -60
-60 + -46
-106
You're just subtracting by 6.
Answer:
The 1/4th power means the 4th root of a number.
Therefore for the first question, the answer should be 4th root of 1296 -4th root of 625. or \sqrt[4]{1296}
4
1296
-\sqrt[4]{625}
4
625
:D
For the second question just calculate? what to the 4th power is 1296 and what to the 4th power is 625?
They should respectively be 6 and 5. So the final answers we get is 6-5=1
