Answer: 1.23×10¹⁶

Step-by-step 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*\frac{999999999}{9+9+9+9+9+9+9+9+9} )^2                [add denominator]

(9*\frac{999999999}{81} )^2                                  [cross multiply]

(\frac{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.
