1000 squared is 100 .........daaa use a calculator
To write powers of a number you write the number, followed by the number of the power in superscript. For example, a number to the second power is x2, a number to the third power is x3 and so on. Squaring is taking a number to the second power. Thus 20 squared is 202, which equals 400.
80 + n^2
