0.4r??

2. LogicalApple

What are you trying to solve for? There is no equation written. Are you just trying to expand it?

3. ASAAD123

$\frac{ 4r^2(2t-3)^3 }{25 }$

4. LogicalApple

Ok. Try distributing the exponent across each factor inside the parentheses. So you will have $2^{3} * (t^{-3})^{3} * (0.4)^{2}r^{2}$

5. LogicalApple

What you have written is correct. Next you should write out what 2^3 is and what 0.4^2 is. And do you know how to handle a negative exponent ?

6. LogicalApple

Yes, that will do it :) What do you get as a final answer?

7. LogicalApple

Yep!

8. LogicalApple

Ha, np. Best of luck with your studies
