Answer:

$\sqrt{225} =15$

Step-by-step explanation:

225÷3=75

75÷3=25

25÷5=5

5÷5=1

then 225 = 3×3×5×5 = 3²×5² = 15²

Since 225 = 15² then $\sqrt{225} = \sqrt{15^{2} }=15$

Solve the equation. Round to the nearest hundredth. Show work.

denis-greek [22]

Answer:

Final answer is approx x=-0.66.

Step-by-step explanation:

Given equation is $5^{-2x-1}=4^{4x+3}$ .

Now we need to solve equation $5^{-2x-1}=4^{4x+3}$ and round to the nearest hundredth.

$5^{-2x-1}=4^{4x+3}$

$\log(5^{-2x-1})=\log(4^{4x+3})$

$(-2x-1)\log(5)=(4x+3)\log(4)$

$-2x \log(5)- \log(5)=4x \log(4)+3 \log(4)$

$-2x \log(5) -4x \log(4)=3 \log(4) +\log(5)$

$x=\frac{\left(3\log(4)+\log(5)\right)}{\left(-2\log(5)-4\log(4)\right)}$

Now use calculator to calculate log values, we get:

$x=-0.65817959094$

Round to the nearest hundredth.

Hence final answer is approx x=-0.66.

Solve for x

vova2212 [387]

$\frac{x-8}{2} =-3$
Common denominator is 2
$\frac{\not2(x-8)}{\not2} =2(-3)$
$x-8=2(-3)$
$x-8=-6$
Add 8
$x=-6+8$
$x=2$
The answer is : D.2
