You're on a roll —
Step 1: Evaluate 32×23×41×31×42.
Group terms with the same base:
(32×31)×23×(41×42)
Apply the rule am×an=am+n:
32+1×23×41+2
33×23×43
Calculate the values:
33=3×3×3=27
23=2×2×2=8
43=4×4×4=64
Multiply these values:
27×8×64
216×64
13824
13824
Step 2: Evaluate 31×5−1×4133×44×5−2.
Group terms with the same base and apply the rule anam=am−n:
(3133)×(4144)×(5−15−2)
33−1×44−1×5−2−(−1)
32×43×5−2+1
32×43×5−1
Calculate the values:
32=9
43=64
5−1=51
Multiply these values:
9×64×51
576×51
5576
5576
Step 3: Find the value of (31)2.
Apply the rule (am)n=amn:
(31)2=31×2=32
Calculate the value:
32=3×3=9
9
Step 4: Expand (23x−1321)−1 and simplify. Write your answer as a positive power.
First, rewrite 321 as 3−2:
(23x−13−2)−1
Apply the outer exponent of −1 to each term inside the parentheses using the rule (abc)n=anbncn and (am)n=amn:
(23)−1(x−1)−1(3−2)−1
23×(−1)x−1×(−1)3−2×(−1)
2−3x132
Rewrite terms with negative exponents as positive exponents using the rule a−n=an1:
2−3=231
So the expression becomes:
231×x×32
23x×32
89x
