Answer 1

Answer:

The Index notation for 3x7x7x7x7 is: $3\times 7^4$

The Index notation for 2x9x9x9x2x9 is: $2^2\times 9^4$

Step-by-step 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.

$3\times 7\times 7\times 7\times 7$

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

Thus, the Index notation is: $3\times 7\times 7\times 7\times 7=3\times 7^4$

Consider the second number.

$2\times 9\times 9\times 9\times 2\times 9$

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

Thus, the Index notation is: $2\times 9\times 9\times 9\times 2\times 9=2^2\times 9^4$
