Question

78 ∙ х 3217, если х = 52 a : 36 + a : 39, если a = 46 х ∙ 37 - в : 25, если х = 15

Answer 1

78 ∙ 52 + 3217=7273;

46/36+46/39=46/(3*12)+46/(3*13)=(46*13+46*12)/3*12*13=1150/468=2 214/468=

=2 107/234;

15*37-b/25=555-b/25

Answer 2

To solve the expression, we need to substitute the given values of x and a in the respective expressions and simplify them.

Given, x = 52 and a = 46

1. 78 ∙ х 3217: Substituting x = 52: 78 * 52 * 3217 = 13444768

2. a : 36 + a : 39: Substituting a = 46: 46/36 + 46/39 = 2.266 + 1.179 = 3.445

3. х ∙ 37 - в : 25: Substituting x = 15: 15 * 37 - v/25 = 555 - v/25

Therefore, the value of the given expression when x = 52 and a = 46 is: 13444768 + 3.445 + 555 - v/25

Note that the value of v is not given, so we cannot simplify the expression any further.
