Simplify x^1/2 times x^2/3

1 answer:

7 0

X^5/6 is the answer to this problem. think of it this way:
2^3 times 2^2 = 8*4 = 32
2^5 = 2*2*2*2*2 = 32
so just add the exponents when the base is the same and youre multiplying

pashok25 [27]

Answer:

0.497

Step-by-step explanation:

Using the binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

From the question :

n = 6 ; x = 3 ; p = 0.42

P(x = 3) +... P(x = 6)

P(x = 3) = 6C3 * 0.42^3 * (1 - 0.42)^(6-3)

P(x = 3) = 20 * 0.074088 * 0.195112

P(x = 3) = 0.28910915712

Then find p(x = 4).. + p(x = 6)

Using a calculator :

P(X >= x) = 0.497

(2a^x + b^x)^2 i need help ASAP

Finger [1]

Answer:

4 $a^{2x}$ + 4 $a^{x}$ $b^{x}$ + $b^{2x}$

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$

Given

(2 $a^{x}$ + $b^{x}$ ) = (2 $a^{x}$ + $b^{x}$ )(2 $a^{x}$ + $b^{x}$ )

Each term in the second factor is multiplied by each term in the first factor, that is

2 $a^{x}$ (2 $a^{x}$ + $b^{x}$ ) + $b^{x}$ (2 $a^{x}$ + $b^{x}$ ) ← distribute both parenthesis

= 4 $a^{2x}$ +2 $a^{x}$ $b^{x}$ + 2 $a^{x}$ $b^{x}$ + $b^{2x}$ ← collect like terms

= 4 $a^{2x}$ + 4 $a^{x}$ $b^{x}$ + $b^{2x}$

Solve x-1/x-4=x+1/x-2 o all real except 2, 4 0 3 no solution

PSYCHO15rus [73]

Solution

Solve

$\frac{x-1}{x-4}=\frac{x+1}{x-2}$

Step 1: Evaluate and cross multiply

$\begin{gathered} \frac{x-1}{x-4}=\frac{x+1}{x-2} \\ x-1(x-2)=x+1(x-4) \\ x^2-2x-x+2=x^2-4x+x-4 \end{gathered}$

Step 2: Collect like terms
