Q2.<br>a) Is the equality √a^4 = a valid for all values of a? Explain.<br>​
allochka39001 [22]

Answer:

The equality is only true for a = 0\ and\ 1, not for all values

Step-by-step explanation:

Given

(\sqrt a)^4 = a

Required

Determine if it is valid

(\sqrt a)^4 = a

Evaluate the exponent

(a^\frac{1}{2})^4 = a

a^\frac{1*4}{2} = a

a^2 = a

Rewrite as:

a^2 - a = 0

Factorize

a(a- 1) = 0

a =0\ or\ a - 1 = 0

a =0\ or\ a = 1

<em>The equality is only true for </em>a = 0\ and\ 1<em>, not for all values</em>

Deion divided 1/2 of a liter of plant fertilizer evenly among some smaller bottles. He put 1/8 of a liter into each bottle. How
Klio2033 [76]

Answer:

4 bottles

Step-by-step explanation:

Given

Fertilizer = \frac{1}{2}L

Bottles = \frac{1}{8}L

Required

Determine the number of bottles

Represent the number of bottles with N

<em>This implies that N bottles of </em>\frac{1}{8}L<em> fit into </em>\frac{1}{2}L<em> of fertilizer. The relationship between them is:</em>

<em></em>Fertilizer =  Bottles * N

\frac{1}{2}L = \frac{1}{8}L* N

\frac{1}{2} = \frac{1}{8}* N

Multiply through by 8

8 * \frac{1}{2} = 8 * \frac{1}{8}* N

4 = 1* N

4 = N

N = 4

<em>Hence, there are  N = 4</em>
