you multiply for example 2to the 5th power =2x2x2x2x2Writing exponents in standard form is simple and easy to do. For every exponent you have to put a zero.
Powers of their exponents
I would say they are in standard form, but I would be more likely just to ask you to write a simplified number without using exponents. The terminology can vary, but the following example shows the usual names: 1,023 is in standard form. One thousand twenty-three is in word form. 1000 + 20 + 3 is in expanded form.
To write 27 in standard form, you would simply write the number as it is, without any exponents or special notation. In this case, 27 in standard form is just 27. Standard form is the most common way of representing numbers and does not involve any additional mathematical operations or symbols.
To convert that to standard notation, write it without the "x 10...", and move the decimal point two digits to the left. (For positive exponents, you would move the decimal point to the right.)
Sixteen thousandths in standard form is written as 0.016. This is because the decimal point is placed after the tenths place (1) and the digit 6 is in the thousandths place. In standard form, we write the numerical value of each place value position without using exponents or other notation.
