Question

23²+(354+7986)[phone]​

Answer 1

23^2+(354-7986)[phone]
1)23^2=529
2)(354-7986)=-7632
3)7986-5678=2308
4)529+(-7632)+2308=-4795

Answer 2

To calculate the expression 23² + (354 + 7986) + 79856 - 5678, you can follow the order of operations (PEMDAS/BODMAS).

PEMDAS stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

BODMAS is similar and stands for Brackets, Orders (i.e., powers and square roots, etc.), Division and Multiplication (left-to-right), and Addition and Subtraction (left-to-right).

Let's solve the expression:

1. First, calculate 23², which is 529.
2. Then, calculate the expression inside the parentheses: 354 + 7986, which is 8340.
3. Now, the expression becomes 529 + 8340 + 79856 - 5678.

Now, you can continue to perform the addition and subtraction operations from left to right:

529 + 8340 = 8869 8869 + 79856 = 88725 88725 - 5678 = 83047

So, the final result of the expression is 83,047.
