The expression 10 x 10 can be simplified using exponents. When a number is multiplied by itself, it is represented using exponents. In this case, 10 x 10 is equal to 10^2. This means that 10 is raised to the power of 2, resulting in 100.
Exponents make the question shorter. Ex: 2.30134 x 106=2301340. Instead of saying 2.30134 x 10 x 10 x 10 x 10 x 10 x 10=2301340
68 = (6 x 10^1) + (8 x 10^0)
2 x 5 = 10 3 x 5 = 15 The implied exponents are 1 and not necessary to write.
10 to the seventh power - or 10,000,000. When multiplying numbers with exponents - you add the exponents together.

640 written in expanded form using exponents is (6 x 10^2) + (4 x 10^1) + (0 x 10^0)
68 = (6 x 10^1) + (8 x 10^0)

5.624 x 10^10?
20 squared = 20 x 20 = 400 400 in expanded form using exponents = (4 x 10^2) + (0 x 10^1) + (0 x 10^0)
6 x 10^2 + 2 x 10^1 + 1 x 10^0
Move the decimal to the right for positive exponents, and the left for negative exponents. 1.23 x 10^3 = 1230 1.23 x 10^-3 = 0.00123
