Solnce55 [7]

Answer:

(B) 2

Step-by-step explanation:

=> $\frac{\sqrt{32}+ \sqrt{48} }{\sqrt{8}+\sqrt{12} }$

=> $\frac{4\sqrt{2}+4\sqrt{3} }{2\sqrt{2}+2\sqrt{3} }$

=> $\frac{4(\sqrt{2}+\sqrt{3}) }{2(\sqrt{2}+\sqrt{3)} }$

Cancelling $\sqrt{2}+\sqrt{3}$

=> $\frac{4}{2}$

The simplified expression of $$4 x \cdot \frac{1}{x^{-5}} \cdot x^{-3}$ is $4x^3$ .

Solution:

Given expression is $4 x \cdot \frac{1}{x^{-5}} \cdot x^{-3}$ .

To simplify the given expression.

$$\Rightarrow4 x \cdot \frac{1}{x^{-5}} \cdot x^{-3}$

Using exponent rule: $\frac{1}{a^{-m}}=a^m$

$$\Rightarrow4x \cdot x^{5}.x^{-3}$

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

$$\Rightarrow4x \cdot x^{5-3}$

$$\Rightarrow4x \cdot x^{2}$

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

$$\Rightarrow4x^{1+2}$

$$\Rightarrow4x^3$

Hence the simplified expression of $$4 x \cdot \frac{1}{x^{-5}} \cdot x^{-3}$ is $4x^3$ .

Jack has 5 craft sticks. He needs 4 times that number for a project.how many craft sticks does jack need altogether?

Katarina [22]

Jack would have twenty craft sticks because four times that number is the same as x4 so you would do 5x4=20.
