Which is expression is equivalent to 6^4 • 6^3?

C) (6x6x6x6)x(6x6x6)

Step-by-step explanation:

an exponent is the base multiplied by itself that many times, and another way to write 2 exponents multiplied by each other (and have the same base) is by simply adding the exponents, for example, 6^4x6^3 is 6^7 :D Hope this helps!

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

the answer is 48m^2!
