Answer:

a*a^{-1}=a*\frac{1}{a}= \frac{a}{a}=1 \\\\a\in R

Step-by-step explanation:

We are talking about the multiplicative inverse of any number. The multiplicative inverse of a number is another number that multiplied by the first, results in the neutral element of the product, that is, the unit. If we have a real number a, then its multiplicative inverse is denoted by a^{-1}, and it is true that:

a*a^{-1}=a*\frac{1}{a}= \frac{a}{a}=1 \\\\a\in R

It's important to note that the multiplicative inverse exists in rational numbers, in real numbers, and in complex numbers.

find the consecutive even integers such that three times the larger number is 30 more than the smaller one. help :')
Minchanka [31]

Answer:

12 and 14

Step-by-step explanation:

Let the even integers be x and x+2

three times the larger number is expressed as 3(x+2)

30 more than the smaller one is x + 30

Equating both expressions

3(x+2) = x +30

Find x

3x+6 = x+30

3x-x = 30-6

2x = 24

x = 12

The second integer is 12+2 = 14

Hence the required integers are 12 and 14

58°

Step-by-step explanation:

(x + 6) \degree + 2x \degree = 180 \degree..(straight \: line \:  \angle s) \\  \\ (3x + 6) \degree = 180 \degree \\  \\ 3x + 6 = 180 \\ \\3x = 180 - 6 \\ \\  3x = 174 \\  \\ x =  \frac{174}{3}  \\  \\ \huge \red{ \boxed{ x = 58}}
