How to you write the number 5,000,000,000,000,000,000,000,000,000,000
tresset_1 [31]
The way you wrote it is how you write it unless you want to do scientific notation then the answer would be, 5x10^30 because for it to be in scientific notation it has to be between 10 and 1 so I moved the decimal spot over 30 to get it into scientific notation. Hope this helps out.

The solution to the given equation is -87/45
<h3>Product of expressions</h3>
Given the following expression that represents the word problem as;
-1/5 * 3 - 12(1/3)^2
Using the PEMDAS rule, the parenthesis and exponent will come first to have;
-1/5 * 3 - 12(1/3)^2 = -1/5 * 3 - 12(1/9)
Then multiplication
-1/5 * 3 - 12(1/9) =. -3/5 - 12/9
Find the difference
-1/5 * 3 - 12(1/9) = -27-60/45
-1/5 * 3 - 12(1/9) = -87/45
Hence the solution to the given equation is -87/45
