A negative exponent becomes POSITIVE in the denominator

.4^-2    =   1/.4^2 =   1/(.16) = 6.25

The answer "cubed"  would lead us back to the thing we took the cube root of....thus

2^3  =  8

Just use the calculator on the home page 

Anyways the answer is 

99/80=1.2375

You can use the Cosine rule which is

CosA= c² + b2- a²/ 2bc 

and the same with B and C

Using law of sines   and law of cosines     yes

Thanks.

So basically the answer cubed is the root?

∛8  =

∛[2 * 2 * 2 ]  =

2

Something like one of these????

25(1.25) + 25(n) = 156.25  ? 

    25n = 156.25 - 25 (1.25)  ?

25n = 125      ?

n = ( 156.25 - 25(1.25) ) / 25   ?

Linkin park in the end best song ever

2^4 * 3^8 = 9^n * 6^4

2^4 * 3^4 * 3^4 = (3^2)^n * 6^4

[ 2 * 3]^4 * 3^4  = (3^2)^n * 6^4

[ 6]^4 * 3^4  = (3^2)^n * 6^4     divide by 6^4

3^4  = (3)^(2n)    solve for the exponents

4  = 2n  →    n = 2

cuz it is

What's N?
