Best Answer

In index form, 90 can be expressed as 9^2. This is because the index form represents the number as a base raised to a power, where the base is 9 and the power is 2. This is equivalent to 9 * 9, which equals 81.

Oh, what a happy little question! In index form, 90 is written as 9 x 10. You see, we just break down 90 into its factors, 9 and 10, to write it in index form. Just like painting a beautiful landscape, sometimes we just need to break things down into smaller, simpler parts to understand them better.
