Firstly,
thanks for posting this.
81 = 9x9 or 9 squared so at this stage I'm guessing the last two.
x^ 8 = (x^ 4) x (x^ 2) (its called the multiplication rule of indices).
Okay I have approx 14 mins to answer.
No panic
√ 81.x^8 x <span>√ y^5
</span>√ (9x^2 x 9x^6) x <span>√ y^5
</span>= 9x x <span>√ 9x^6 x </span><span>√ y^5
</span>did I just gain time?
√ 9x^6 = <span>√ </span>3x ^3 x <span>√ 3x ^ 3
</span>or 2 . √ 3x^3. <span>√ y^5
</span>more time
okay, so that wasnt successful.
√ 9x^6 =<span>√ </span> (3x^2) x <span>√ </span>(3x^4)
1,2,4
24/1 = 24 84/1=84 88/1=88
24/2=12 84/2=42 88/2=44
24/4=6 84/4=21 88/4=22
Answer:
c.) hourly rate
Step-by-step explanation:
The value the coefficient represents can often be learned from its units. The term 8t gives a value in currency units, since the expression 8t+20 is an amount that is to be paid. (We can only add like terms, so both 8t and 20 must have currency units.)
The value of t has units of hours, so the coefficient 8 must have units that are ...
8 currency units/hour
That is, multiplying by hours gives currency units.
In this context, a number with units of <em>currency units per hour</em> is most likely the hourly rate of the rental.
