Answer:
x = 2
Step-by-step explanation:
Taking antilogs, you have ...
2³ × 8 = (4x)²
64 = 16x²
x = √(64/16) = √4
x = 2 . . . . . . . . (the negative square root is not a solution)
___
You can also work more directly with the logs, if you like.
3·ln(2) +ln(2³) = 2ln(2²x) . . . . . . . . . . . write 4 and 8 as powers of 2
3·ln(2) +3·ln(2) = 2(2·ln(2) +ln(x)) . . . . use rules of logs to move exponents
6·ln(2) = 4·ln(2) +2·ln(x) . . . . . . . . . . . . simplify
2·ln(2) = 2·ln(x) . . . . . . . . . . . subtract 4ln(2)
ln(2) = ln(x) . . . . . . . . . . . . . . divide by 2
2 = x . . . . . . . . . . . . . . . . . . . take the antilogs
Working out the expression 7(3ˣ) is first to calculate the value of 3ˣ then multiply the answer to 7.
For example, let x = 2
Then 7(3ˣ) = 7(3²) = 7 × 9 = 63
With the same value of x = 2, calculating 21ˣ = 21² = 441, which isn't the same answer with the expression 7(3ˣ)
A)The reels did the electrician check out from the storeroom is 16 reels.
B) 800 feet of cable were checked our from the storeroom, if each reel has 50 feet of wire.
C) 730 feet of cable did the electrician use on the job.
Given that during the course of working on a wiring job, an electrician checks out the following cable stocks from the storeroom: 5 reels, 3 reels, 1 reel, 3 reels, and 4 reels. at the end pf the job he returns to the storeroom 1 full reel and a partial reel with 20 feet remaining.
The total number of reels are 16 in the store room and each reel is of 50 feet . As a result total reel has 800 feet and at last he left with 1 reel and 20 feet reels so that reel that left is 730 feet
Therefore,A)The reels did the electrician check out from the storeroom is 16 reels.
B) 800 feet of cable were checked our from the storeroom, if each reel has 50 feet of wire.
C) 730 feet of cable did the electrician use on the job.
