What is the value of x in the equation 25x2 = 16. A. 5/4. B. 4. C. 4/5. D. 16/25

Sergeeva-Olga [200]

Answer:

x = ⅘

Step-by-step explanation:

For clarity, exponents should be marked with a ^. 25x² can be written as 25x^2.

25x² = 16

divide both sides by the 25

x² = 16/25

take the square root of both sides

x = √(16/25) = √16/√25 = 4/5
