Question from Alina, a student:

My question says to express each number in exponent form in as many different ways as I can; 16, 81 and 64. How do I do this?

Hi Alina,

Let me try 125. I think this is what is expected.

$125 = 5 \times 5 \times 5$ and hence you can write

$125 = 5^0 \times 5^3$ $125 = 5^1 \times 5^2$ $125 = 5^1 \times 5^1 \times 5^1$

$125 = 5^0 \times 5^3$

$125 = 5^1 \times 5^2$

$125 = 5^1 \times 5^1 \times 5^1$
