Find the values of a , b and c in the equation below
stellarik [79]

Answer:

x^12 y^2 z^11

a= 12

b= 2

c= 11

Step-by-step explanation:

On the numerator you distribute the exponent 3 to the other exponents.

I think you multiply the 3 so you would get: x^15 y^3 z^12.

so it looks like x^15 y^3 z^12 / x^3yz

Then you subtract the top exponents from the bottom exponent because when you are dividing you subtract exponents. the exponent for y and z in the denominator is 1

and thats how i got x^12 y^2 and z^11. The exponents are a b and c

I hope that is right

Need help quick simplify the expression (-4) power of 3
dezoksy [38]

Answer:

-64

Step-by-step explanation:

The question is asking to solve (-4)^3

Notice how the -4 is in parenthesis. This means that along with the 4 being multiplied, the negative is too.

(-4)^3 is the same as -4 · -4 · -4

First let's figure out if this will be negative or positive

Whenever the exponent is odd and there is a negative in the parenthesis the answer will be negative and if its even it will be positive

Now find out what 4 x 4 x 4 equals (64)

In conclusion the answer is -64
