The general form for a term with fractional exponents is given as :
![a^{ \frac{m}{n} }](https://tex.z-dn.net/?f=a%5E%7B%20%5Cfrac%7Bm%7D%7Bn%7D%20%7D)
which can be rewritten as
![(\sqrt[n]{a} )^m](https://tex.z-dn.net/?f=%20%28%5Csqrt%5Bn%5D%7Ba%7D%20%29%5Em)
for example:
Answer:
= 8n - 19
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 11 and d = - 3 - (- 11) = - 3 + 11 = 8, thus
= - 11 + 8(n - 1) = - 11 + 8n - 8 = 8n - 19
Answer:
< and
and ![\neq](https://tex.z-dn.net/?f=%5Cneq)
Step-by-step explanation:
-7 is less than -4
-7 is less than -4, so less than or equal to works too. Because it is or, it works in this scenario.
-7 is also not equal to -4
Answer: 80, 40
Step-by-step explanation: I just made an equation which went something along the lines Of 3.1x=248 , then you get 80, then 40.
