Answer:

The value is 20.

Step-by-step explanation:

To solve this equation, you must use the method of PEMDAS.  In this order, you should multiply 8 by 2 first to get 16 for the first part of your answer.  Your equation should now be 7 + 16 - 6 + 3.  You can now solve this equation from left to right manually.  Add 16 from 7 to get 23, subtract 6 from that number to get 17 and add 3 to get your final answer which is 20.

The cylinder is 10 meters wide and the volume is 300 cubic meters what's the height of the cylinder?
daser333 [38]
Cylinder is 10 meters wide, so its diameter is 10 meters. You get radius of it by dividing 10 by 2, which equals 5.
As you count volume of cylinder from that equation
V=A*h= \pi  r^{2}*h 
You get an equation to count height:
h= \frac{V}{ \pi  r^{2} } 
h≈3.82 meters

Ugo [173]
The formula for finding circumference is Pi multiplied by diameter.

3.14 x 25ft = 78.5 feet

This would round up to 79 feet in circumference.

Use the properties of exponents to simplify the expression: 2532
Vlad1618 [11]

Question

Use the properties of exponents to simplify the expression: 25^{\frac{3}{2}}

Answer:

25^{\frac{3}{2}} = 125\

Step-by-step explanation:

Given

25^{\frac{3}{2}}

Required

Simplify

25^{\frac{3}{2}}

Apply the following law of indices

a^{\frac{m}{n}} = (a^m)^{\frac{1}{n}}

So, the expression becomes

25^{\frac{3}{2}} = (25^3)^{\frac{1}{2}}

Express 25^3 as 15625

25^{\frac{3}{2}} = (15625)^{\frac{1}{2}}

In indices: a^{\frac{1}{2}} = \sqrt a

So, we have:

25^{\frac{3}{2}} = \sqrt{15625

25^{\frac{3}{2}} = 125
