In the box you have given no. 64 two times but the method of the both number and answer are different. Why like that?
Number | Expanded form | Exponential form | Base and exponent |
10000 | 10 × 10 × 10 × 10 | 104 | base 10 exponent 4 |
base exponent 5 | |||
64 | 2 × 2 × 2 × 2 × 2 × 2 | 26 | base 2 exponent 6 |
64 | (–2) × (–2) × (–2) × (–2) × (–2) × (–2) | (–2)6 | base –2 exponent 6 |
–32 | (–2) × (–2) × (–2) × (–2) × (–2) | (–2)5 | base –2 exponent 5 |
Let us solve some more examples to understand the concept better.
Example 1:
Write the following in exponential form
a. Minus nine to the power of six
