Question

[25,(99)]+[7,(9)]^2-[9.9]=?

Answer 1

Буду считать, что в условии [] означают целую часть числа. Тогда [25,(99)]+[7,(9)]^2-[9.9]=25+7²-9=25+49-9=65

Answer 2

To solve this expression, we need to follow the order of operations (also known as PEMDAS) which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

So let's break down the expression step by step:

1. First, we need to evaluate the square of (7,9), which means we need to multiply each of the values inside the parentheses by itself:

(7,9)^2 = (7^2, 9^2) = (49, 81)

2. Next, we need to add the result of step 1 to the first term in the original expression:

25 + (99) + (49, 81) = (25 + 99 + 49, 99 + 81) = (173, 180)

3. Finally, we need to subtract 9.9 from the result of step 2:

(173, 180) - 9.9 = (173 - 9.9, 180 - 9.9) = (163.1, 170.1)

Therefore, the final answer is (163.1, 170.1).
