Hi! I was wondering if you could help with this question please :)

Answer:

$R=\frac{QJ}{I^2t}$

Step-by-step explanation:

So we have the equation:

$Q=\frac{I^2Rt}{J}$

And we want to solve for R.

First, let's multiply both sides by J to remove the fraction on the right. So:

$(J)Q=(J)\frac{I^2Rt}{J}$

Simplify the right:

$JQ=I^2Rt$

We can rewrite our equation as:

$JQ=R(I^2t)$

So, to isolate the R variable, divide both sides by I²t:

$\frac{JQ}{I^2t}=\frac{R(I^2t)}{I^2t}$

The right side cancels, so:

$R=\frac{QJ}{I^2t}$

And we are done!

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-4" was replaced by "^(-4)".

Step by step solution :

Step 1 :

Equation at the end of step 1 :

0-(((9•(a2))•(b6))•(0-7ab(-4)))

Step 2 :

Equation at the end of step 2 :

0 - ((32a2 • b6) • -7ab(-4))

Step 3 :

Final result :

(32•7a3b2)
