A 5-digit password lock has 10 options for each digit slot. How many combinations are possible, and what exponential form represents this?
Show answer
1,00,000; 10^5
Each of the 5 digit slots has 10 choices, so total combinations are 10 × 10 × 10 × 10 × 10 = 10^5 = 1,00,000.
A 3-digit lock and a 2-digit lock are compared. What is the difference in the number of combinations between them?

900
A 3-digit lock has 1000 combinations and a 2-digit lock has 100 combinations. The difference is 1000 - 100 = 900.
A line of length 2^4 units is halved 10 times. What is the final length in simplest form?
Show answer
1/64 unit
The length becomes 2^4 ÷ 2^10 = 2^(4-10) = 2^-6 = 1/2^6 = 1/64 unit.
A paper thickness starts at 0.001 cm. After 3 folds, what is the thickness, and what factor increase does that represent?
