for this do i add the two and 3 or do i multiply? also do i multiply the 8 by the 3?

Answer 1

u multiply

Answer 2

\[(8x^2)^3=8^3x^{2*3}=8^3x^6=512x^6\]

Answer 3

well you need split it 1st

\[(8x^2)^3 = 8^3 \times (x^2)^3\]

the power of a power rule for indices says

\[(x^a)^b = x^{a \times b}\]

this should help to simplify your question
