Question

What is 625 in exponential notation.

Answer 1

6.25*10^2

Answer 2

Ok, so you know you have 625, you can see that you can take 25 out, which is a perfect square, so you divide 625 by 25 and you get 25, and then you know that 25 is 5x5 so, since you have 2 25's, that means your have 4 5's, so your answer is 5^4. I'm sorry if that's confusing.

Answer 3

lol in a much simpler way:

5 x 5 x 5 x 5 = 625, so we have (4) 5's, so we write it like :

\[= 5^4\]

Answer 4

how did you find that out sstarica?

Answer 5

we have 625 and our number ends with a 5, so 5x5= 25, another 5x5 = 25, so 25 x 25 = 625 ^_^

Answer 6

it is easy you must only find the common factors o the number just like 625 is divisible by 5 so 5 * 5 and 5 * 5 * 5 * 5 so it is =\[5^{4}\]
