7²-0,4×5

Answer

To solve this expression, we'll follow the order of operations, which is PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

7² means 7 raised to the power of 2, which is 49.

Next, we have 0.4 multiplied by 5, which is 2.

So, the expression becomes:

49 - 2

Subtracting 2 from 49 gives us:

47

Therefore, 7² - 0.4 × 5 equals 47.
