Answer 2

The Index notation for 3x7x7x7x7 is:
`3* 7^4`

The Index notation for 2x9x9x9x2x9 is:
`2^2* 9^4`

Explanation:

Consider the provided number.

3×7×7×7×7 and 2×9×9×9×2×9

We need to write the number in index notation.

Index notation is shortcut method of writing repeated multiplications by the same number.

Consider the number.

`3* 7* 7* 7* 7`

Here, 3 repeat 1 time and 7 repeat 4 times.

Thus, the Index notation is:
`3* 7* 7* 7* 7=3* 7^4`

Consider the second number.

`2* 9* 9* 9* 2* 9`

Here, 2 repeat 2 times and 9 repeat 4 times.

Thus, the Index notation is:
`2* 9* 9* 9* 2* 9=2^2* 9^4`
