The body of a 154-pound person contains approximately 2 x 10^-1 milligrams of
gold and 6 x 10^1 milligrams of aluminum. Based on this information, the number of
milligrams of aluminum in the body is how many times the number of milligrams of gold
in the body?

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
