Question

(3m+ 1/5)^2 =?

please answer ​

Answer 1

Step-by-step explanation:

(a+b)^2 = a^2 + b^2 + 2ab

(3m+1/5)^2 = 9m^2 + 1/25 + (6/5)m

Answer 2

Step-by-step explanation:

Given :-

[3m +(1/5)]²

To find :-

Expand the expression ?

Solution :-

Given expression is [3m +(1/5)]²

It is in the form of (a+b)²

Where, a = 3m

and b = 1/5

We know that

(a+b)² = a²+2ab+b²

Now,

[3m +(1/5)]²

=> (3m)²+2(3m)(1/5)+(1/5)²

=> 9m²+(6m/5)+(1/25) or

LCM of 5 and 25 = 25

=> (225m²+30m+1)/25

Answer:-

[3m +(1/5)]² = 9m²+(6m/5)+(1/25) or (225m²+30m+1)/25

Used Identity :-

→ (a+b)² = a²+2ab+b²
