Solved Examples
Example 1: Jack is multiply a number through itself. If the product is 77, help Jack discover the number.
Solution:
To find the number, let united state assume the number come be zOn multiplying z times z = z × z = 77z² = 77z = √77z = 8.77(8.77 × 8.77 = 76.9129 ≅ 77)The number is 8.77.
Example 2: The area of a square-shaped table is 5929 square units. Calculation the size of one side of the table.
Solution:
The area of the table = 5929 sq. UnitsTo uncover the next of a square-shaped table, let us take square source of 5929 by prime factorization method.√5929 = √(7 × 7 × 11 × 11) = 7 × 11Square source of 5929 is 77.Therefore, the length of the side of the square table is 77 units.
Example 3: assist Joy find the square root of 77 as much as 3 decimal places.
Solution:
Step 1: beginning from the right, we will pair up the number 77 by place a bar over 77. Us will additionally pair the six 0s in decimals in bag of 2 from left to right.Step 2: discover a number that, as soon as multiplied come itself, offers a product less than or same to 77. The number 8 fits right here as 8 square gives 64. Separating 77 by 8 with quotient as 8, we obtain the remainder together 13.Step 3: drag a pair that 0’s down and also place them next come 13 to do the dividend 1300.Step 4: dual the divisor 8 and location 16 below with a empty digit come its right. Think of a number i m sorry is greater than or same to the dividend, i.e. 1300. 167 is the perfect number to divide 1300.Step 5: multiply 167 by 7 (167 × 7 = 1169 Step 6: Repeat this process up to three decimal places.
