Yogita Ingle 5 years, 5 months ago

Rule 1: When the numbers having the same base are multiplied, add the exponents.

a^p × a^q = a^(p+q)

a = base : p,q = exponents

Rule 2: When the numbers having the same base are divided, subtract the exponents.

a^p ÷ a^q = a^{(p-q)} i.e. a = base: p,q = exponents

Rule 3: Multiply the powers when the numbers are raised by another number.

(a^p)^q= a^{(pxq)} =a^{(pq)}

The parallel sides of an isosceles trapezium = 40 cm and 20 cm. The equal sides = 26 cm. The distance between the parallel sides = [26^2-{(40–20)/2}^2]^0.5 = [676–10^2]^0.5 = (676–100)^0.5 = 576^0.5 = 24 cm. Area of trapezium = (40+20)*24/2 = 720 sq cm.

What is the maximum exterior angle possible for a regular polygon ?

Posted by Prakash Rabidas 5 years, 5 months ago

CBSE > Class 08 > Mathematics

1 answers

Meghna Thapar 5 years, 5 months ago

An exterior angle is an angle which is formed by one of the sides of any closed shape structure such as polygon and the extension of its adjacent side. Exterior angles of a polygon are formed when by one of its sides and extending the other side. The sum of all the exterior angles in a polygon is equal to 360 degrees.

Each exterior angle of an equilateral triangle is 120 degrees and hence this the maximum possible value of the exterior angle of a regular polygon. This can also be proved by another principle; which states that each exterior angle of a regular polygon is equal to 360 divided by the number of sides in the polygon. If 360 is divided by 3, we get 120. So 120 degrees the highest exterior angle for a regular polygon.

What is the smallest number by which the following numbers must be multipled, so that the products are perfect cubes? : a. 675 b. 1323 c. 2560 d. 7803

Posted by Rakshita Deshpande 5 years, 5 months ago

CBSE > Class 08 > Mathematics

1 answers

Yogita Ingle 5 years, 5 months ago

(i) 675

675 = 3 × 3 × 3 × 5 × 5 = 3³× 5²

∴To make a perfect cube we need to multiply the product by 5.

(ii) 1323

1323 = 3 × 3 × 3 × 7 × 7 = 3³ × 7²

∴To make a perfect cube we need to multiply the product by 7.

(iii) 2560

2560 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 5 = 2³ × 2³ × 2³ × 5

∴To make a perfect cube we need to multiply the product by 5 × 5 = 25.

(iv) 7803

7803 = 3 × 3 × 3 × 17 × 17 = 3³ × 17²

∴To make a perfect cube we need to multiply the product by 17.

Yogita Ingle 5 years, 5 months ago

Least Length of Cube =10

Volume of cube =10³=1000

Dimensions of cuboid =5 × 2 × 5

Volume of cuboid =5 × 5 × 2 = 50

So number of Cuboid required to make a cube =1000/50=20 cuboids

Thus, 20 cuboids of dimensions 5×2×5 are,required to make a cube
