Answer 1

Answer:

192.8 gn and thanks for the points

Answer 2

Answer:

Required answer is $30 \frac{14}{25}$

Step-by-step explanation:

Given,2 upon 5 into 13 into 3 upon 5 into 13 - 10

$\frac{2}{5} \times 13 \times \frac{3}{5} \times 13 - 10$

By BODMAS rule, we can solve this problem.

By BODMAS rule ,

Bracket -Of - Division - Multiplication - Addition - Subtraction

So,

$\frac{2}{5} \times 13 \times \frac{3}{5} \times 13 - 10 \\ = \frac{2 \times 13 \times 3 \times 13}{5 \times 5} - 10 \\ = \frac{1014}{25} - 10 \\ = \frac{1014 - 25 \times 10}{25} \\ = \frac{1014 - 250}{25} \\ = \frac{764}{25} \\ = 30 \frac{14}{25}$

This is a problem of Algebra.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
