Question

I hate math can someone please help me

Answer 1

To change the negative to a positive, just put the same number as into a fraction under 1 but without the negative sign:

11^-4 would become 1 / 11^4

Answer 2

Don't hate math! It can be scary, but if you crush big problems in smaller ones, everything gets simple :)

Take exponents, for example: I suppose you know how to deal with positive exponents: you multiply the base times itself as many times as the exponent commands: for example,

$4^3 = 4 \times 4 \times 4 = 64$

Because the base is 4 and the exponent is 3, so you multiply 4 by itself 3 times.

Now, negative exponents work exactly the same, except you have to perform all of these operations at the denominator. Here's the same example as before, but with negative exponent:

$4^{-3} = \dfrac{1}{4^3} = \dfrac{1}{4\times 4 \times 4} = \dfrac{1}{64}$

See? Exactly the same as before, except it happened at the denominator.

So, in your example, the negative exponent simply means that you have to perform the exponentiation at the denominator, so

$11^{-4} = \dfrac{1}{11^4}$
