The answer to your question is 9 x 9 = 81.
Answer:
fraction > -18/5
dec> -3.6
Step-by-step explanation:
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
Answer:
A = 8
B = 6
C = 4
D = 7
Top = 29
Side = 20
Step-by-step explanation:
To get A on the bottom side row you divide 32 by 4 and get 8.
To get D, on the first side row, subtract A, 8, now it's 21, 21 divided by 3 is 7.
To get B, on the first top row, subtract A and D, now divide by 2 and you get 6.
To get C, on the third side row, subtract B and divide by 2 and you get 4.
