Find the value of the expression below. Express your answer in scientific notation.

nirvana33 [79]

The value of the expression is $8.8 \times 10^{-2}$ .

Solution:

Given expression:

$$\frac{\left(4.8 \times 10^{8}\right)}{\left(1.2 \times 10^{4}\right)} \times\left(2.2 \times 10^{-6}\right)$

To find the value of the given expression:

Using exponent rule: $a^m\times a^n=a^{m+n}$

$$\Rightarrow\frac{\left(4.8 \times 10^{8-6}\right)}{\left(1.2 \times 10^{4}\right)} \times\left(2.2 \right)$

$$\Rightarrow\frac{\left(4.8 \times 10^{2}\right)}{\left(1.2 \times 10^{4}\right)} \times\left(2.2 \right)$

Using exponent rule: $\frac{a^m}{a^n} =a^{m-n}$

$$\Rightarrow\frac{\left(4.8 \times 10^{2-4}\right)}{1.2} \times 2.2$

$$\Rightarrow\frac{\left(4.8 \times 10^{-2}\right)}{1.2} \times 2.2$

Since $\frac{4.8}{1.2}=4$

$$\Rightarrow(4 \times 10^{-2})\times 2.2$

$$\Rightarrow 8.8 \times 10^{-2}$

Hence the value of the expression is $8.8 \times 10^{-2}$ .

If a and b are two digits, then the following fraction

Andrews [41]

Answer:

B. 1010

Step-by-step explanation:

Simplify:

(ab0+ab0ab) ÷ (ab) - 1

Note that:

ab = 10a +b
ab0 = 10* (10a + b) = 10ab
ab0ab = 1000ab + ab = 1001 ab

Therefore:

(ab0+ab0ab) ÷ (ab) - 1 =
(10ab + 1001ab) ÷ (ab) - 1 =
(1011ab) ÷ (ab) - 1 =
1011 - 1=
1010

Correct choice is B.1010

vagabundo [1.1K]

Answer:

See the graph of the given linear equation shown below.

Explanation:

Given the linear equation : x+y = -2

We make a table for values of x and y;

x y = -2-x

0 -2

-2 0

1 -3

Now, plot these three points (0, -2) , (-2, 0) and (1, -3) on the coordinate plane.

You can see the graph as shown below.

4^2/4^6 Options: 4^-3 4^3 4^-4 4^4

Vlad [161]

Hello!

The rule regarding the division of exponents states the following:

$\frac{ B^{x} }{ B^{y} }$ = $B^{x-y}$

Insert any known values into the formula above:

$\frac{ 4^{2} }{ 4^{6} }$ = $4^{2-6}$

Simplify the expression:

$4^{2-6}$ = $4^{-4}$

We have now proven that $\frac{ 4^{2} }{ 4^{6} }$ is equal to $4^{-4}$ .

I hope this helps!
