25 POINTS!! Help will give the brainliest
polet [3.4K]

Answer:

value of a in terms of b and c is: \mathbf{a=bc}

Option D is correct.

Step-by-step explanation:

We are given:

a=b^2c^2d \:and\: d=\frac{1}{a}

We need to find a in terms of b and c

We have: a=b^2c^2d

Put value of d d=\frac{1}{a}

a=b^2c^2(\frac{1}{a})\\a^2=b^2c^2\\Taking \:squareroot\:on\:both\:sides\\\sqrt{a^2}=\sqrt{b^2c^2}\\a=bc

So, value of a in terms of b and c is: \mathbf{a=bc}

Option D is correct.
