How to solve this plss frac{(\sqrt{(3)})^{5}}{((\sqrt{(3)})^{-4})}=(\sqrt{(3)})^{(2k+1)

dusya [7]

Answer:

k = 4

Step-by-step explanation:

Given equation:

$\dfrac{(\sqrt{3})^{5}}{(\sqrt{3})^{-4}}=(\sqrt{3})^{(2k+1)}$

$\textsf{Apply exponent rule} \quad \dfrac{a^b}{a^c}=a^{b-c}:$

$\implies (\sqrt{3})^{(5-(-4))}=(\sqrt{3})^{(2k+1)}$

$\implies (\sqrt{3})^{9}=(\sqrt{3})^{(2k+1)}$

$\textsf{Apply exponent rule} \quad a^{f(x)}=a^{g(x)} \implies f(x)=g(x):$

$\implies (\sqrt{3})^{9}=(\sqrt{3})^{(2k+1)}$

$\implies 9=2k+1$

$\implies 2k=8$

$\implies k=4$

The snack bar at the park sells an average of 1.2×10^5 drinks per year and it sells an average of 4.0×10^4 hot dogs per year.

lozanna [386]

Answer:

8.0 × 10⁴

Step-by-step explanation:

1.2 × 10⁵ - 4.0 × 10⁴

1.2 × 10⁵ = 120000

4.0 × 10⁴ = 40000

120000 - 40000 = 80,000

8.0000 (4 spaces)

8.0 × 10⁴
