Question

PLEASE HELP Type in expanded form. Use parentheses to indicate multiplication. (2r)³

Answer 1

It would be 8$r^{3}$ because you have to multiply the exponent by each of the numbers exponents. you may not see it but 2 has a 1 as an exponent and so does r. 1 time 3 is 3 for each therefore each number now has an exponent of 3 and we got rid of the outside exponent. now all you have to do is simplify the 2 to the power of 3 which gives you 8 and that is all

Answer 2

I think the answer would be 2000
