Question

find and evaluate the following.. ​

Answer 1

Answer:

i) m+1/m= 5

Step-by-step explanation:

${m}^{2} + \frac{1}{ {m}^{2} } = 23$

(m+1/m)²= m²+(1/m)²+2×m×1/m

[using identity (a+b)²= a²+b²+2ab]

(m+1/m)²= m²+1/m²+2

(m+1/m)²= 23+2

(m+1/m)²= 25

m+1/m= √25

m+1/m= 5

Hope It Helps :)

Answer 2

Answer:

i) m+1/m= 5

Step-by-step explanation:

(m+1/m)²= m²+(1/m)²+2×m×1/m

[using identity (a+b)²= a²+b²+2ab]

(m+1/m)²= m²+1/m²+2

(m+1/m)²= 23+2

(m+1/m)²= 25

m+1/m= √25

m+1/m= 5
