Answer:

c^7/9

Step-by-step explanation:

basically when ever you need to turn a root into an exponent create a fraction where the root number (number on the left in the little dip) is the denominator and the exponent already on the number is the numerator.

so since 9 is on the root, and 7 is the exponent already there, our rational exponent is 7/9.

How do you work out the length of radius and diameter of these two circles?

bogdanovich [222]

So for the first one what you did was wrong as in wrong formula.
Radius is 5cm as it is given and diameter is double the radius which is 10.
So r=5
And D=10.

For the second one the diameter is 16cm as it is given and radius is half the diameter,so half of 16 is 8cm right?
So r=8
And D=16

(a-7)(a-3) as a function

stiv31 [10]

Answer:

a^2 −10a+21

Step-by-step explanation:

(a−7)(a−3)

Apply the distributive property by multiplying each term of a−7 by each term of a−3.

a^2 −3a−7a+21

Combine −3a and −7a to get −10a.

a^2 −10a+21
