Question

Обчисліть значення виразу √25-3х, якщо х=3

Answer 1

Ответ:

25-3×3=25-9=16 и корень из 16 равен 4

Answer 2

To calculate the value of the expression √(25 - 3x) when x = 3, you simply need to substitute the value of x into the expression and perform the arithmetic operations.

Given: x = 3

Expression: √(25 - 3x)

Now, substitute the value of x:

√(25 - 3 * 3)

Now, perform the arithmetic operation:

√(25 - 9)

√16

The square root of 16 is 4.

So, the final result is:

√(25 - 3x) = 4
