80 + n^2
No but 81 is a square number
Adding four percent to a number is the same as multiplying the number by 1.04. In this instance, 1.04 x 80 = 83.2. therefore, 80 increased by 4 percent is equal to 83.2.

take the number and multiply it by .8 like .8x100 (80 percent of 100) = 80
The increase is 60%

80,000,000 is 80 million in number form.
I think you are looking for 36
80 billion = 80,000,000,000
The increase is 60%
take the number and multiply it by .8 like .8x100 (80 percent of 100) = 80
802 = 80 x 80 = 6400
Here's another way to ask the question: If you have a number and increase it by 40 percent you get 80. What is the number? Let x be the number you're looking for. Forty percent of the number can be expressed as 0.40x (because 40% = 0.40). The question said that x is increased by 40 percent, which implies addition, so the equation is x + 0.40x = 80 1.4x = 80 x = 80/1.4 = 57.14
80,000,000,000,000,000,000,000
Eighty.
