Question

a=11, b=5 multiplicative inverse of ab is​

Answer 1

Answer:

Required multiplicative inverse of ab is $\frac{1}{55}$

Step-by-step explanation:

Here given,a=11 and b=5

Here we want to find multiplicative inverse of ab.

Now

$ab = 11 \times 5 \\ = 55$

But now question is what is Multiplicative inverse?

We know,

Multiplicative inverse is an element of a mathematical set that when multiplied by a given element yields the identity element. — called also reciprocal.

If x is a number then multiplicative inverse of x is $\frac{1}{x}$

For example -

Multiplicative inverse of 2 is $\frac{1}{2}$

Multiplicative inverse of 20 is $\frac{1}{20}$

Multiplicative inverse of 100 is $\frac{1}{100}$

Multiplicative inverse of $\frac{2}{3}$ is $\frac{3}{2}$

Multiplicative inverse of $\frac{1}{25}$

is $25$

Here number is 55.

So Multiplicative inverse of 55 is $\frac{1}{55}$

Therefore Multiplicative inverse of ab is $\frac{1}{55}$

Answer 2

Answer:

The multiplicative inverse of ab is 1/55.

Step-by-step explanation:

Multiplicative inverse:-

• The reciprocal of the given number is called the multiplicative inverse.

Step 1 of 1

Given:-

The value of a = 11 and b = 5.

To find:-

The multiplicative inverse of ab.

According to the question,

a = 11 and b = 5

Consider the product of a and b as follows:

⇒ ab

⇒ 11 × 5

⇒ 55

Then,

The multiplicative inverse of the ab is,

= 1/ab (The reciprocal of ab)

So, the reciprocal of the number 55 is,

= 1/55

Therefore, the multiplicative inverse of ab is 1/55.
