The picture below would be 3 to the power of 3 right? Edit: Or would it be 3 to the power of 2?

The 3×3 notation means 3 by 3 or 3 times 3 = 3². The exponent two can be thought of as the number of spatial dimensions in this case.

I have another question. How would you write 1000 as a power of 10?

1000 = 10³ 1000 written in base r is r³. Just count the zeros to get the exponent.

1000 = 10·10·10 10³ = 10·10·10 In this case 10 is the base and 3 is the exponent. The exponent tells you how many times the base is a factor. 3² = 3·3 = 9 2^(10) = 2·2·2·2·2·2·2·2·2·2 = 1024 x·x·x·x = x^4 x²·x² = x^4 (a^b)·(a^c) = a^(b + c) 4^(5) = (2²)^5 = 2^10 (a^b)^c = a^(bc)

Mathematical skills should start to develop before any school, let alone high school.
