zaharov [31]3 years ago

\log_4(\log_42x)=1

Take both sides as powers of 4:

4^{\log_4(\log_42x)}=4^1\implies\log_42x=4

Do it again:

4^{\log_42x}=4^4\implies2x=(2^2)^4=2^8\implies x=2^7=128

Next, exponents.

36³ is 46656.

Then, multiplication.

7 · 9= 63

After that, division.

63 ÷ 9 is 7

Finally, subtraction.

46656 - 7 is 46649

Square root of 22801 by long division method
mezya [45]
First step: partition the number you want to square root into a block of 2 digits, starting from the last digit (first diagram)

Second step: As our number is a five-digits, we ends up with 2  28  01. Pick a number that could be squared to get the first partition, 2. This number is 1, since 1×1=1

Third step: Write 1 on the top and on the side, as shown in the second graph

Fourth step: Double the number on the side, which is 1+1=2 and use this number as the first digit for the next multiplier. Meanwhile, subtract 1 from 2 inside the root sign to get 1, then pull the other two digits, 28

Fifth step: We need a value in the boxes that when we multiply together will give a number less than 128. We choose 5 as 25×5=125

Sixth step: Subtract 125 from  128 to give 3, and as the same concept with long division, bring down the 0 and the 1. So we have 301

Seventh step: Add 5 to the multiplier on the left, so 20+5=30, which we will use on the side as the hundred and ten digits.

Final step: Find a number to fit in the boxes. We choose 1 since 301×1=301

And hence the square root of 228801 is 151

Cindy has a salary of $880 per week and is paid every two weeks. She has the following deductions from each paycheck: Federal in
Nitella [24]

Answer:

244.80 If I'm not wrong.

Step-by-step explanation:

Add all of the deductions together and subtract them by 880

By using g00gle I found out that 195.82 + 63.60 + 134.64 + 176.00 = 635.24.

So now you subtract it by her salary down below:

880.00 - 635.24 = 244.76  

244.80 or 245 if I'm not wrong
