Answer 1

Hey there! Those look like exponents. So, 2^8 (2 to the eighth power) is 2*2*2*2*2*2*2*2. Basically, the number multiplied by itself the amount of times the exponent is. Does that make sense?

Answer 2

\[\Large a^m \times a^n = a^{m+n}\]

Answer 3

\[\Large 2^3 \times 2^5 = 2^{3 + 5} = 2^8\]

Answer 4

So it's 2^8 ?

ohh ok
