(–4)(–4)

amistre64 · Answer

multiplication is a more concise way of writing addition, k added n times:$$k+k+k+...+k=nk$$

exponents are a more concise way of writing multiplication k multiplied n times...
$$k*k*k*k*...*k=k^n$$

amistre64 · Answer

so, first determine you value of k

then determine how many times it is being multiplied to itself, n

either you do not understand my explanation, or you perfer others to do your thinking for you ...

anonymous · Answer

no I don't understand you. and I like to do my own thinking thank you :)

nincompoop · Answer

look at the patterns:

(5)(5)(5) = 5^3
here, your exponent is 3. meaning that 5 has been multiplied three times.

(-10)(-10)(-10)(-10)(-10) = (-10)^5
here, your exponent is 5. meaning that (-10) has been multiplied five times.

(a)(a) = (a)^2
here, your exponent is 2. meaning that (a) has been multiplied twice. 

@amistre64  showed you something with k instead of a. these letters are just place holders, meaning they could be any value. it is the same concept, the k has been multiplied by how many times it appeared in the equation. he used n as a placeholder for the exponents to indicate that n will be how many times k will be multiplied.
