Question

Does anyone have idea, how to count big exponentiation not using calculator? For example:
`5^7` how can i solve it in head (if its hard at least on paper)

Answer 1

Answer: To solve
`5^(7)` without a calculator think of this formula
`a^(n)`. a is the base of the exponentiation while n is the exponent.

We multiply the base by itself n times, so in this case, we multiply 5 by itself 7 times.

Explanation:

`5^(7) =78125`

5 × 5 × 5 × 5 × 5 × 5 × 5 = 78125

5 × 5 = 25

25 × 5 = 125

125 × 5 = 625

625 × 5 = 3125

3125 × 5 = 15625

15625 × 5 = 78125
