I don't know how to do this

This is the concept of sequences and series. To solve the question we proceed as follows:
2] T=-4n-3
to get the 11th term we substitute n=11 in the expression and simplify. Thus, plugging in n=11 we obtain:
T=-4(11)-3
T=-44-3
T=-47
thus the 11th term is -47

3] General term is T=n²-1. The 7th term will be evaluated as above:
plug in n=7 in the expression and simplify:
T7=7²-1
T7=49-1
T7=48
thus the 11th term is 48

4] General sequence is T=1/3n². The term will be evaluated as follows:
plug in n=3 in the expression and simplify:
T3=1/(3×3²)=1/27
Thus the 3rd term is 1/27

Evaluate the expression. [(3–5)(34)]3 1 Innermost group, apply the product of powers: [3–1]3 2 Apply the power of a power: 3–3 3
Otrada [13]

Answer:

x=27

Step-by-step explanation:

To evaluate the expression: [(3^{-5})(3^4)]^3

Step 1:  Innermost group, apply the product of powers (a^x \times a^y =a^{x+y}

Therefore:

(3^{-5})(3^4)=3^{-5+4}=3^{-1}

We then have:

=[3^{-1}]^3

Step 2: Apply the power of a power

[3^{-1}]^3=3^{-1 \times 3} =3 ^{-3}

Step 3: Apply the negative exponent

3 ^{-3} =\dfrac{1}{3^3}

Step 4: Simplify

\dfrac{1}{3^3}=\dfrac{1}{27}

Therefore, the value of x in the simplified expression is 27.
