Question

Express each of the following numbers using exponential notation:
1) 512
2) 343
3) 729
4) 3125
​

Answer 1

Answer:

$512 = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 = {2}^{9 } \\ 343 = 7 \times 7 \times 7 = {7}^{3 } \\ 729 = 3 \times 3 \times 3 \times 3 \times 3 \times 3 = {3}^{6 } \\ 3125 = 5 \times 5 \times 5 \times 5 \times 5 = {5}^{5}$

Answer 2

Step-by-step explanation:

1) 512 = 3√512 = 8³

2) 343 = 3√343 = 7³

3) 729 = 3√729 = 9³

4) 3125 = 5√3125 = 5⁵
