Question

What is the value of x in the equation 25x2 = 16?

Answer 1

25x2 = 16
x^2 = 16/25
x^2 = 4^2/5^2
x = 4/5

Answer 2

Answer:

The answer is

$x=(+/-)\frac{4}{5}$

Step-by-step explanation:

we have

$25x^{2}=16$

Solve for x

Divide by $25$ both sides

$25x^{2}/25=16/25$

$x^{2}=16/25$

Square root both sides

$x=(+/-)\sqrt{\frac{16}{25}}$

$x=(+/-)\frac{4}{5}$
