Solve fy:-625^-frac{3{4}}

$$f y : - 625 ^ { - \frac { 3 } { 4 } }$$

Evaluate

$$-125fy$$

Solution Steps

Calculate 625 to the power of -\frac{3}{4} and get \frac{1}{125}.

$$\frac{fy}{-\frac{1}{125}}$$

Divide fy by -\frac{1}{125} by multiplying fy by the reciprocal of -\frac{1}{125}.

$$\frac{fy\times 125}{-1}$$

Anything divided by -1 gives its opposite.

$$-fy\times 125$$

Multiply -1 and 125 to get -125.

$$-125fy$$

Differentiate w.r.t. f

$$-125y$$
