How do you solve root 23?
Estimation and Approximation
- Step 1: Find a perfect square which is smaller than and bigger than 23.
- Step 2: Writing in terms of inequality- 4<√23<5 = 16<23<25.
- Step 3: Multiply by 10 and write in terms of square roots- √1600<√2300<√2500.
- Step 4: Move closer to inequality- √2209<√2300<√2304 = 47<10√23<48.
