The multiplicative inverse of 3 in z4
WebSolution: Assume (1+2x). (1+2x) (1 +2x).(1+ 2x) (1 + 2x)^2 = 1 + 4x + 4x^2 = 1. (1+2x)2 = 1+4x +4x2 = 1. The inverse of 2x + 1 2x +1 in Z_4 [x] Z 4[x] is 2x + 1 2x +1. Thus, the polynomial 2x + 1 2x+1 in Z_4 [x] Z 4[x] has a multiplicative inverse in Z_4 [x] Z 4[x]. Need a fast expert's response? Submit order WebMultiplicative Inverse Calculator.

WebFor example, with whole numbers, 15 is equivalent to 15/1 (15 over 1). To get that, you multiply by the multiplicative inverse of 15 - in this case, 1/15, by the original number, getting 1. Swapping the numerator and the denominator is the same concept. So for 4/5 (4 over 5), you would multiply it by 5/4 (5 over 4). find the hiding cat owlsWebThe multiplicative inverse of $3$ in $\Bbb Z/7\Bbb Z$ is $5$, since $3 \times_7 5 = 5 \times_7 3 = 1$.
