Symbol, unit and unit conversion of resistance

The resistance of a conductor is usually expressed by the letter R. the unit of resistance is Ohm (ohm for short), and the symbol is Ω (Greek alphabet, transliterated into pinyin to read as ō u m ī GA). 1 Ω = 1V / A. the larger units are kiloohm (K Ω) and megaohm (m Ω) (trillion = million, i.e. 1 million)

11. Let me ask you a question that you have answered before. Is it possible that the equation (2M2 + M-3) x ^ (M + 1) + 5x = 13 of X is a quadratic equation of one variable? The degree on X is m + 1 one (2m²+m-3)x^(m+1)+5x=13 If it is a quadratic equation of one variable, two conditions should be satisfied 1）m+1=2,m=1 2)2m²+m-3≠0 When m = 1, the above formula = 2 + 1-3 = 0, which does not meet the requirements So it can't be a quadratic equation of one variable two It's similar to the question M-1 = 2, then M = 3 Substituting M = 3 into 2m & # 178; + M-3, we get: 2m²+m-3=2×9+3-3=18≠0 So this could be a quadratic equation of one variable How does m + 1 become M-1 = 2, then M = 3 Substituting M = 3 into 2m & # 178; + M-3, we get: 2m²+m-3=2×9+3-3=18≠0 So this could be a quadratic equation of one variable
