Question

@phi another:

Answer 1

\[r=7\sqrt{t}\]
would be:
\[t=\frac{ r ^{2} }{ 7 }\]
?

Answer 2

I would divide both sides by 7 (to get the t by itself)
\[ \frac{r}{7}= \sqrt{t} \]

now square both sides (to get rid of the square root)
what do you get?

Answer 3

t=r^2/7
would both the top and bottom be squared or just the top?

Answer 4

square means multiply by itself:
\[ \frac{r}{7}\cdot \frac{r}{7}= \sqrt{t} \cdot \sqrt{t}\]

Answer 5

so 2r on top?

Answer 6

When multiplying fractions, you multiply top times top, and bottom times bottom

r*r can be written as \( r^2\)
It is short-hand, and it's more useful for r*r*r*r*r, written as \(r^5\)
notice that r+r = 2r (1 r plus another r gives you 2 r's)

Answer 7

ahhhh sooo.. r^2/49?

Answer 8

yes
