Solve c =(a² + 3b)/4 for b.<br><br>Bruv take all my points I literally blow at math :'(​
Sati [7]

Answer:

b=\frac{4c-a^{2} }{3}

Step-by-step explanation:

First: multiply both sides by 4. 4 times c is 4c and the other sides cancels out as you are doing the inverse operation of division

Then, you have 4c=a^{2} +3b

Subtract both sides by a squared

DO NOT TAKE THE SQUARE ROOT! This is because it is a squared plus 3b so you have to do the inverse of addition

From that you get 4c-a^{2} =3b

Finally, divide both sides by 3.

You get  b=\frac{4c-a^{2} }{3}

How do you Simplify (3a^2)^3
mamaluj [8]
When a number with an exponent is raised to an exponent, you multiply the two exponents together to get the combined exponent of the simplified version.
Let's take our exponents, 2 and 3, and multiply them.

2 x 3 = 6

Therefore we can apply the sixth power to 3a for our final answer of 3a⁶.

Hope this helped!
