I need help on a quetion

Readme [11.4K]

The given fuctions are:

$\begin{gathered} f(x)=3^x \\ g(x)=f(x+1) \end{gathered}$

this means that for the reference it is:

$g(x)=3^{x+1}$

now for the first coordinate it is:

$g(0)=3^{0+1}=3$

then:

$g(1)=3^{1+1}=9$

then:

$g(2)=3^{2+1}=27$

Finally

$g(3)=3^{3+1}=81$

Need help answering this one

Step-by-step explanation:

$(\frac{8.4.2}{8.7} )^{2} \times (\frac{ {8}^{0} }{{7}^{ - 3} } )^{3 } \times {7}^{ - 9} \\ \\ = (\frac{8}{7} )^{2} \times (\frac{ 1}{{7}^{ - 3} } )^{3 } \times {7}^{ - 9}..... (\because a^0=1)\\ \\ = \frac{64}{49} \times ({{7}^{ 3} } )^{3 } \times {7}^{ - 9} \\ \\ = \frac{64}{49} \times {{7}^{ 3 \times 3} } \times {7}^{ - 9} \\ \\ = \frac{64}{49} \times {{7}^{ 9} } \times {7}^{ - 9} \\ \\ = \frac{64}{49} \times {{7}^{ 9 - 9} } \\ \\ =\frac{64}{49} \times {{7}^{ 0} } \\ \\ =\frac{64}{49} \times 1 \\ \\ = \frac{64}{49}$

Thus, first option is the correct answer.
