Choose the correct simplification of the expression f to the 6th power times h to the 9th power all over f to the 3rd power times h to the 7th power.

(f*6 h^9)/(f^3 h^7) =
The exponent rule for division is 'keep the base and subtract the powers'
f^3 h^2

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.
