Best ResponseYou've already chosen the best response.25+sqrt{x} is same as 5+sqrt{x} over one \[\huge\rm \frac{5+\sqrt{x}}{1} +\frac{1}{1+x}\] so what is the common denominator

Best ResponseYou've already chosen the best response.2yes right so when we find common denominator we should multiply the numerator of 1st fraction by the denominator of 2nd fraction and multiply the numerator of 2nd fraction by the denominator of 1st fraction (just like cross multiply\[\huge\rm \frac{ (1+x)(5+\sqrt{x} )+1(1)}{ 1+x }\] )dw:1442176038130:dw

Best ResponseYou've already chosen the best response.2yes right now combine like terms \[\huge\rm \frac{ 5+\sqrt{x}+5x+x\sqrt{x}+1}{ 1+x }\] )

Best ResponseYou've already chosen the best response.0(6 +5x + xsqrt(x) + sqrt(x)) / (1+x)

Best ResponseYou've already chosen the best response.2yes right there is one more step you can convert square root to 1/2 \[\huge\rm \frac{ 5+\sqrt{x}+5x+ \color{red}{x\sqrt{x}}+1}{ 1+x }\] ) \[\huge\rm \frac{ 5+\sqrt{x}+5x+ \color{red}{x^1 \times x^{\frac{1}{2}}}+1}{ 1+x }\] ) apply the exponent rule when we multiply same bases we should add their exponents

Best ResponseYou've already chosen the best response.2\[\huge\rm x^m \times x^n=x^{m+n}\] so \[\huge\rm x^1 \times x^{\frac{1}{2}}=??\]
