Answer:
multiply their coefficients, use the base with the sum of exponents
Step-by-step explanation:
The coefficients multiply. The base gets an exponent that is the sum of the exponents of the factors.
(a·x^b)(c·x^d) = ac·x^(b+d)
_____
If you remember that an exponent is simply an indicator of the number of times the base is a factor, this should be fairly clear. The usual associative and commutative properties of multiplication apply.
<u>Example</u>
5x^2 · 7x^3= 5·x·x·7·x·x·x
= 5·7·x·x·x·x·x
= (5·7)(x^(2+3))
= 35x^5
Answer:
320
Step-by-step explanation:
Well, the volume of a pyramid is 1/3 b * h
What is the height of one of these pyramids? Well, they tell you that it's 10. What is the base? It's 6 * 8 = 48
10 * 48 * 1/3 = 160
Now multiply by 2 because there are two pyramids. One on top and one one bottom. 160 * 2 = 320
It’s an expression. there is no like terms within the expression so it remains the same. each variable is different because of either the “a, b, x, y” or the squared.

Step-by-step explanation:
The equation of the circle would be (x−(−4))2+(y)2=6or (x+4)2+(y−72=36.
Explanation:The equations of the circle is(−h)2+y−k)2=r2
where h is the x of the center of the circle and k is the y of the center of the circle, and r is the radius(-4,7) radus is 6h = -4k = 7r = 6plug in the values(x−(−4))2+(y−7)2=62simplify(x+4)2+(y−7)2=36.
