We Need To Remember Order of Operations.

So, We Do:
4+5.
We Know That 4 + 5 = 9, So We Have:
9 ÷ 3 * 4
Now, We Do:
9 ÷ 3
This Is 3, So We Have:
3 * 4.
We Know That 3 * 4 Is 12, So:

We Know That The Answer To This Expression Is 12.

Which expression is equivalent to log2 9x^3?

marishachu [46]

Answer:

Option 1 - $\log_{2}(9 {x}^{3} )=\log_{2}(9 ) +3 \log_{2}( {x} )$ - log Subscript 2 Baseline 9 + 3 log Subscript 2 Baseline x

Step-by-step explanation:

Given : Expression $\log_2(9x^3)$

To find : Which expression is equivalent to given expression ?

Solution :

Expression $\log_2(9x^3)$

Applying logarithmic property, $\log_{a}( MN ) = \log_{a}( M) + \log_{a}( N )$

$\log_{2}(9 {x}^{3} ) = \log_{2}(9 ) + \log_{2}( {x}^{3} )$

Using property, $\log_{a}( { M}^{n} ) =n \log_{a}( { M})$

$\log_{2}(9 {x}^{3} )=\log_{2}(9 ) +3 \log_{2}( {x} )$

i.e. log Subscript 2 Baseline 9 + 3 log Subscript 2 Baseline x

Therefore, option 1 is correct.

The length of the rectangle is 2x + 8 cm and the width is 2cm . The area of the rectangle is 12 cm

Ksju [112]

Answer:

x = - 1

Step-by-step explanation:

Length ( l ) = 2x + 8 cm

Width / Breadth ( b ) = 2 cm

Area ( rectangle ) = 12 cm

Formula : -

Area ( rectangle ) = lb

12 = ( 2x + 8 ) ( 2 )

Divide 2 on both sides,

12 / 2 = ( 2x + 8 ) ( 2 ) / 2

6 = 2x + 8

2x + 8 = 6

2x = 6 - 8

2x = - 2

x = - 2 / 2

x = - 1
