Question:-
1) 18^10= 4^5 * 3^x Find x
2) if (3^2x+1 ) + 9 / 9 = 10 then find x

Answer 1

${18}^{10} = {4}^{5} \times {3}^{x} \\ {(9 \times 2)}^{10} = { ({2}^{2} )}^{5} \times {3}^{x} \\ {( {3}^{2} \times 2)}^{10} = {2}^{10} \times {3}^{x} \\ {3}^{20} \times {2}^{10} = {2}^{10} \times {3}^{x} \\ {3}^{20} = {3}^{x} \\ 20 = x \:$
