What is the simplified value of the exponential expression 16^1\4
Natalka [10]

If you observe that 16 = 2^4, you can rewrite the expression as

16^{\frac{1}{4}} = (2^4)^{\frac{1}{4}}

Now, if you use the exponent rule (a^b)^c = a^{bc}, you may rewrite the expression again:

(2^4)^{\frac{1}{4}} = 2^{4\cdot\frac{1}{4}} = 2^1 = 2

The explicit formula for a sequence is<br> an=−2+3/2(n−1)<br> What is the 21st term of the sequence?
Anni [7]

Step-by-step explanation:

From the given question it appears that (n-1) is in the numerator's place, if it is so, then let us solve it.

a_n =  - 2 +  \frac{3}{2}(n - 1)   \\ \\  \therefore \: a_{21} =  - 2 +  \frac{3}{2}  (21 - 1) \\  \\   \therefore \: a_{21} =  - 2 +  \frac{3}{2 }   \times \: 20\\  \\ \therefore \: a_{21} =  - 2 + 3 \times \: 10  \\  \\ \therefore \: a_{21} =  { -2  + 30}   \\  \\ \therefore \: a_{21} =  28   \\  \\  \huge \red{ \boxed{\therefore \: a_{21} =   28}  } \\  \\
