There’s a shortcut to help you work with base 10 numbers and exponents:
The exponent tells you how many zeros are in the whole number.
For example, you know that 10² = 10 × 10 = 100
100 has 2 zeros.
10³ or 10 × 10 × 10 equals 1,000, which has 3 zeros.
10⁴ or 10 × 10 × 10 × 10 equals 10,000, which has—you got it!—4 zeros.
This holds true for any number that’s a multiple of 10. For example, the number 10,000,000,000,000 has 13 zeros and can be written as 10¹³.
