Question 382936
solve for x: log x + (log x + 21)=2


log x + (log x + 21) = 2
thinking you meant log x + 21 and not log (x + 21), sorry if this was not the case
2log x + 21 = 2
2log x = -19
log x = -19/2 = -9.5
logarithmic rule: if logb x = y, then b^y = x
assuming base is 10
10^(-9.5) = x
3.162278 * 10^(-10) rounded places after the decimal point to 6 places
