Please give me the answer and explaination?

70 f^6 g^2 - h

Step-by-step explanation:

10f^2gh, 35f^3g^2 = lcm = 10 and 35 = 10/35 = 0.285714286 multiplier   0.285714286 * ( 35/2) = 5   then 35/5 = 7  then multiply by 10 = 70  or you need to add up prime of product remainders and similar as counted  as = (1 * similar)       f^2 and f^3 is the sae as 2 and 3 = 6 = f^6  and g^1 and g^2 = 1 and 2 = 2 =^2 then -h     Note when working with 2 lots of unit numbers to find the lowest multiple it only works to see the prime of products are 2+3 = 6  while greatest multiple of 2 + 3 = 1   so  3+4 = 1 too for greatest multiple while 3 +4 = 12 we show as 3 *4 = 12 and 2*3 = 6 for lowest multiple's  

wait nvm i know the correct answer now its 100%   81 square feet
