Answer 2

Step-by-step explanation:

Solutions:-

i) Given number = 3^-5

We know that

a^-n = 1/a^n

=> 3^-5

=> 1/(3^5)

=> 1/(3×3×3×3×3)

=> 1/243

3^-5 = 1/243

Multiplicative inverse of 1/243 is 243

Multiplicative inverse of 3^-5 is 3^5 or 243

ii) Given number = 4^-3

We know that

a^-n = 1/a^n

=>4^-3

=> 1/(4^3)

=> 1/(4×4×4)

=> 1/64

4^-3 = 1/64

Multiplicative inverse of 1/64 = 64

Multiplicative inverse of 4^-3 = 4^3 or 64

iii) Given number = x^-n

We know that

a^-n = 1/a^n

=>x^-n

=> 1/x^n

x^-n = 1/x^n

Multiplicative inverse of 1/x^n is x^n

Multiplicative inverse of x^-n = 1/x^n is x^n

iv) Given number = 1/4^3

=> 1/(4×4×4)

=> 1/64

1/4^3 = 1/64

Multiplicative inverse of 1/4^3 =1/64 is 4^3 or 64

Answer:-

i)Multiplicative inverse of 3^-5 is 3^5 or 243

ii)Multiplicative inverse of 4^-3 = 4^3 or 64

iii)Multiplicative inverse of x^-n = 1/x^n is x^n

iv)Multiplicative inverse of 1/4^3=1/64 is 4^3 or 64

Used formulae:-

• a^-n = 1/a^n

• The product of two non zero numbers is 1 then they are called the multiplicative inverses to each other.

Ex:-

The Multiplicative Inverse of a = 1/a

Since = a×(1/a)=a/a = 1

Where, 1 is the multiplicative Identity element.
