Squares and powers, step by step
An exponent is a shorthand for repeated multiplication.
The question
7²
7²
7²=7 × 7
7²=7 × 7
7 × 7=49
- The small number is a COUNT, not something to multiply by. 7² does not mean 7 × 2 — it means how many 7s to multiply together.
- So write it out: 2 7s multiplied together — 7 × 7.
- Now it is just multiplying: 7 × 7 = 49.
