To write 420 in exponent form, you would express it as 4.2 x 10^2. This is because 420 can be broken down into 4.2 multiplied by 100, which is equivalent to 10^2. Exponent form is a way to represent a number as a base raised to a certain power, in this case, 10 raised to the power of 2.

You cannot. There are thought to be fewer than a googol atoms in the known universe so you cannot even write a googol in number form: you can only write such large numbers in exponent form.
