Fill in the blank.<br> (5x)2<br> a0x2
Yuki888 [10]

Answer:a_0=25

Step-by-step explanation:

It is given that, (5x)^2=a_0x^2

We need to find the value of a_0

As (5x)^2=a_0x^2

Solving LHS

25x^2=a_0x^2

Now comparing the coefficients of x^2

In LHS the coefficient of x^2 is 25

In RHS the coefficient of x^2 is a_0

It implies that, a_0=25

So, the value of a_0 is 25.
