Use the rules of division for complex numbers. Just divide 1 / (4 + 3i). This requires multiplying numerator and denominator of this fraction by (4 - 3i), to get a real number in the denominator.
0.25
1/4 is the multiplicative inverse of 4
Suppose the multiplicative inverse is x. Then x*4 = 1 Divide both sides by 4: x = 1/4 or 0.25
The multiplicative inverse is 1 / 0.25, equal to 4.
It means, "With what number must I multiply it, to get a product of 1?" For example, the multiplicative inverse of 4 is 0.25 (= 1/4), since 4 x 0.25 = 1. The multiplicative inverse of 5/17 is 17/5. In general, you can divide 1 by a number to get its multiplicative inverse; in the case of fractions, first convert the fraction to an improper fraction (if it is in the form of a mixed fraction), then simply exchange numerator and denominator.
7
The multiplicative inverse of 4i is -(1/4)*i.
0.25
A multiplicative inverse is the same as a reciprocal. The multiplicative inverse of x is 1/x. So, the multiplicative inverse of 4 is 1/4; or 7 is 1/7 and of 0.2 is 1/0.2 = 5.
If y is equal to -4 there is not a multiplicative inverse. If y is different than -4 the inverse is: -1/(4+y)
To find the multiplicative inverse of a complex number z = (a + bi), divide its complex conjugate z* = (a - bi) by z* multiplied by z (and simplify): z = 4 + i z* = 4 - i multiplicative inverse of z: z* / (z*z) = (4 - i) / ((4 - i)(4 + i) = (4 - i) / (16 + 1) = (4- i) / 17 = 1/17 (4 - i)
1/4 is the multiplicative inverse of 4
4.
Suppose the multiplicative inverse is x. Then x*4 = 1 Divide both sides by 4: x = 1/4 or 0.25
-4
-4 multiplicative inverse of -0.25 is 1/-0.25 which is -4
a multiplicative inverse is the same as a reciprocal so basically just flip it over:3/4 would be 4/3
