Answer:

See below

Step-by-step explanation:

So basically the product is the result of mulyplying ---> factor × factor = product. You need to replace the values given so basically

8 ×2/5(0.40) =3.2 which is between 0 and 8, making the first statement true. Hopefully, this gives you an idea on how to answer the rest!!

Use logarithms to solve each equation 2x9/8=111

Illusion [34]

<span>We have this equation:
</span>
$2x^{\frac{9}{8}} = 111$

and we need to find the value of x.

First of all, we multiply the whole equation for 1/2, so our goal is to isolate x, therefore:

$x^{\frac{9}{8}}=\frac{111}{2}$

Next step we must do is to apply <span>logarithms:
</span>
$logx^{\frac{9}{8}} = log(\frac{111}{2})$

Next, we have to apply identities and then to solve the equation:

$\frac{9}{8}logx = log(\frac{111}{2})$
$logx = \frac{8}{9}log(\frac{111}{2})$
$logx = 1.5504$
$10^{logx} = 10^{1.5504}$

Finally, we have the value of x which was our goal. This is the answer for the question above:

$x= 35.5140$

Could some please help me with these two

damaskus [11]

Answer:

Step-by-step explanation:

(-m)^(-3) = -m^3, since (-1)^-3 = 1 / (-1).

If m = 2 then we have -2^(-3), or -1 / [2^3]), or -1/8.

Finally, if n = -24, the original expression becomes

(-1/8)(-24) = +3

Second problem: Only the first expression simplifies to a negative result.
