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 $4x^3$ .

Hello!!!

The Graph's Answer is below

Nicole's Pattern Ian's Pattern Coordinate's Plane

1 0 ( 1,0)

5 1 (5,1)

17 3 (17,3)

53 7 (53,7)

161 15 (161,15)

In order to get these answers, you start with 1 one Nicole's equation, and mutliply by 3, which gets you three. You then add two, which gets you five, after this, you continue to add Nicole's answer by three, then add five.For Ian's answer,you start with 0,then you add 1/2, which gives you .5 After you have this .5 you multiply by 2,which gives you one whole, you continue to add a half and mutliply by 2 for each answer. Nicole's answer is X,which means it is used first in our parentheses ( ),while ian's is Y and is used second.

I HOPE THIS HELPS! Good luck on your assignment and let me know if you need help with anything else <3!

Find the lest number which is exactly divisible by 36 & 90 Maths

prisoha [69]

Answer:

Step-by-step explanation:

You need to find the HCF of 36 and 90.

Prime factors of each:

36 = 2*2*3*3
90 = 2*3*3*5

HCF includes all prime factors of both numbers:

HCF(36, 90) = 2*2*3*3*5 = 180
