0.00000000000081

Step-by-step explanation:

So first what you want to do is 10 to the negative 7th power which is 0.0000001. Then you want to multiply that by 9 because of PEMDAS which is Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. After multiplying 0.0000001 by 9 you get 0.0000009. Now you multiply 0.0000009 by 0.0000009 which gives you 0.00000000000081. You multiply 0.0000009 by itself because of the small 2 in the upper right hand corner! Hope this helps! Have a great day
