Mice21 [21]

Answer:

{(1 + x)}^{ \frac{3}{2} }  -  {(1 + x)}^{ \frac{1}{2} }

factorise out (1 + x)^½ :

=  {(1 + x)}^{ \frac{1}{2} }[ ( {1 + x)}^{3}  - 1)] \\  =  {(1 + x)}^{ \frac{1}{2} } [(1 + 2x +  {x}^{2} )(1 + x) - 1] \\  =  {(1 + x)}^{ \frac{1}{2} } [(1 + 2x +  {x}^{2}  +  x + 2 {x}^{2}  +  {x}^{3} ) - 1] \\  =   {(1 + x)}^{ \frac{1}{2} } [ {x}^{3}  + 3 {x}^{2}  + 3x ] \\  { \boxed{= x( {x}^{2}  + 3x + 3)(1 + x) {}^{ \frac{1}{2} } }}

Write each number in standard form:<br> 300,000+5,000+80+8· 1/100 +9· 1/10,000
Zepler [3.9K]

The standard form of the number is 305080.0089

<u>Explanation:</u>

Given:

300,000 + 5,000 + 80  + 8X\frac{1}{100} + 9 X \frac{1}{10000}

This can be further written as:

300,000 + 5,000 + 80 + 0.008 + 0.0009

Adding all the terms we get:

300,000 + 5,000 + 80 + 0.008 + 0.0009 = 305080.0089

Therefore, the standard form of the number is 305080.0089
