Karnataka Board Class 8 Maths Chapter 5 Squares, Square Roots, Cubes, Cube Roots Ex 5.5<\/h2>\n

Question 1.
\nFind the nearest integer to the square root of the following numbers.
\n(i) 232
\n(ii) 600
\n(iii) 728
\n(iv) 824
\n(v) 1729
\nAnswer:
\n(i) 232
\n232 lies between 225 = (15\u00b2) and 256 = ( 16\u00b2)
\n232 – 225 = 7 and 256 – 225 = 31
\n7 < 31
\n\u2234 \u221a232 is nearest to 15.<\/p>\n

Question (ii)
\n600
\nAnswer:
\n600 lies between 5 76 (=24\u00b2) and 625 (= 25\u00b2)
\n600 – 576 = 24 and 625 – 600 = 25
\n24 < 25
\n\u2234 \u221a600 is nearest to 24.<\/p>\n

Question (iii)
\n728
\nAnswer:
\n728 lies between two square
\nNo. 676 and 729
\n676 = 26 \u00d7 26
\n\u2234\u221a676 = 26
\nand 729 = 27 \u00d7 27
\n\u2234 \u221a729 = 27
\nNow 728 is nearer to 729.
\n\u2234\u221a728 is 27<\/p>\n

Question (iv)
\n824
\nAnswer:
\n824 lies between 784=(28\u00b2) and 841 =(29\u00b2)
\n824 – 784 = 40 and 841 – 824= 17
\n17 < 40
\n\u2234 \u221a824 is nearest to 29.<\/p>\n

Question (v)
\n1729
\nAnswer:
\n1729 lies between 1681 = (41\u00b2) and 1764 = (42\u00b2)
\n1729 – 1681 =48 and 1764- 1729 = 35
\n35 < 48
\n\u2234 \u221a1729 is nearest to 42.<\/p>\n

Question 2.
\nA Piece of land is in the shape of a square and its area is 1000 m\u00b2. This has to be fenced using barbed wire. The barbed wire is available only integral lengths. What is the minimum length of the barbed wire that has to be bought for this purpose?
\nAnswer:
\nIf l is the side length of a square its perimeter is 4l.
\nGiven that l\u00b2= 1000
\nHence (4l)\u00b2= 16l\u00b2 = 16 x 1000 = 16000
\n126\u00b2 = 15876 < 16000 < 16129= 127\u00b2
\n15876 is nearer to 16000 than 16129. The approximate value of \u221a16000 is 126.
\nThe Approximate Value of the perimeter is 126 m.
\nIf the length of the wire is 126 m it may fall short.
\n\u2234 The length of the wire to be bought is 127m.<\/p>\n

Question 3.
\nA student was asked to find V961. He read it wrong and found V691 to the nearest integer. How much small was his number from the correct answer?
\nAnswer:
\n\u221a961 = 31 is the correct answer 31
\n\"KSEEB
\n26\u00b2 = 676 < 691 <729 =27\u00b2
\n691 – 676 = 15 and 729 – 691 =38
\n\u221a691 is nearer to 26
\nThe student \u221a691 = 26 found. The correct answer is 31.
\n\u2234 The difference is 31 – 26 = 5
\nThe number is smaller than the correct answer by 5.<\/p>\n","protected":false},"excerpt":{"rendered":"
