Wats 200 + 142

Only genius can answer this!!!

Lol

2a+7+4ahow many terms? how many variables? any like terms? yes noif yes, which ones? what are the coefficients? any constants? yes noif yes, which ones? simplify the expression by combining like terms and constants: how many terms now?

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b

Write the equation in logarithmic form e^x=403.429
