Question

Dare to solve it so easy ☺️​

Answer 1

Answer: 1.23×10¹⁶

Explanation:

For this problem, we want to use order of operations to solve.

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

Let's first solve the parenthesis.

`(9*(999999999)/(9+9+9+9+9+9+9+9+9) )^2` [add denominator]

`(9*(999999999)/(81) )^2` [cross multiply]

`((999999999)/(9) )^2` [divide]

`(111111111)^2` [exponent]

1.23×10¹⁶

The ending result is way too large. Therefore, we use scientific notation and get 1.23×10¹⁶.
