If you're asking how to simplify, then this is how you do it.
when a power meets another power but in brackets, then you have to multiply the powers. ¼ × 4 would be 1. i simplified 81 to 3⁴.
The formula for determining the pressure, p, exerted on an object at a depth, h, below the surface of a liquid is p = s + dgh, where s is the atmospheric pressure, d is the density of the liquid, and gas the acceleration due to gravity.
p = s + dgh
dgh = p - s
h = (p - s)/dg
Which formula represents h in terms of p, s, d, and g? Formula B is correct.
20 multiplied (times) 4 is equal to 80 c:
= 3 ⋅ 2
= 6 is the rational numbe
