Question

I want the whole calculation. Pls give!!!​

Answer 1

Answer:

2

Step-by-step explanation:

Let , given term  $\frac{[0.75 + (0.75)^2 +1]}{[1-(0.75)^3]}$  = X

We have to calculate the value of √(X)

Let, 0.75 = a

Now, the term is $\frac{[a + (a)^2 +1]}{[1-(a)^3]}$

$=\frac{[a + (a)^2 +1]}{[(1-a)(1+a+a^2)]}$      [  as,  1 - a³  =  1³- a³  = (1-a)(1+a+a²)  ]

$=\frac{1}{1-a}$

$=\frac{1}{1-0.75}$         [  as, a = 0.75 ]

$=\frac{1}{0.25}$

= 4

Finally, square root of X = √(X) = √4 = 2

Hope you have got the whole calculation ☺☺☺☺☺☺☺.
