scZoUnD [109]

Answer:

Step-by-step explanation:

$16.2=2.7(h+1)\\\\2.7\left(h+1\right)=16.2\\\\\mathrm{Multiply\:both\:sides\:by\:}10\\2.7\left(h+1\right)\cdot \:10=16.2\cdot \:10\\\\Refine\\27\left(h+1\right)=162\\\\\mathrm{Divide\:both\:sides\:by\:}27\\\frac{27\left(h+1\right)}{27}=\frac{162}{27}\\\\Simplify\\h+1=6\\\\\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}\\h+1-1=6-1\\\\Simplify\\h=5$

Adjust the number into correct standard form. 4381 × 10 3

ZanzabumX [31]

Answer:

the standard form of the given number is 4.381 x 10⁶

Step-by-step explanation:

Given number = 4381 x 10³

The above number can also be written as; 4381.0 x 10³

In standard form, the decimal point will be moved three steps backward to the first digit (4) and the resulting is multiplied by 1000, as shown in the number below;

4381.0 x 10³ = 4.381 x 10³ x 1000

= 4.381 x 10⁶

Thus, the standard form of the given number is 4.381 x 10⁶
