Question

Find the value of

b) (5*5)+15/3​

Answer 1

Explanation:

An electroscope is an early scientific instrument used to detect the presence of electric charge on a body. It detects charge by the movement of a test object due to the Coulomb electrostatic force on it. The amount of charge on an object is proportional to its voltage. 

Answer 2

Explanation:

$(5 \times 5) + \frac{15}{3}$

$= 25 + 5$

$= 30$
