Question

Найдите значение выражений: 3•a, a : 2, 8•a, a•5, если а = 8.

Answer 1

3*8=24
8/2=4
8*8=64
8*5=40

Answer 2

To find the values of the expressions for a = 8, simply substitute the value of a into each expression and perform the calculations:

1. 3•a = 3 * 8 = 24
2. a : 2 = 8 / 2 = 4
3. 8•a = 8 * 8 = 64
4. a•5 = 8 * 5 = 40

So, the values of the expressions are:

1. 3•a = 24
2. a : 2 = 4
3. 8•a = 64
4. a•5 = 40
