If each face has an area of 4 than the side lengths are 2, because area is b•h and 2•2 is 4. Now, volume is length•width•height. All of these will be two because sides are the same in a cube. 2•2•2 is 8, which is your answer

Answer:

Jim's error is " He did not multiply Three-fifths by 2 before applying the power "

Step-by-step explanation:

Jim's evaluating expression is $2(\frac{3}{5})^3$

To verify Jim's error :

Jim's steps are

$2(\frac{3}{5})^3$

$=2(\frac{3^3}{5})$

$=2(\frac{3\times 3\times 3}{5})$

$=2(\frac{27}{5})$

$=\frac{54}{5}$

Therefore $2(\frac{3}{5})^3=\frac{54}{5}$

Jim's error is " He did not multiply Three-fifths by 2 before applying the power "

That is the corrected steps are

$2(\frac{3}{5})^3$

$=2(\frac{3^3}{5^3})$ ( using the property $(\frac{a}{b})^m=\frac{a^m}{b^m}$ )

$=2(\frac{3\times 3\times 3}{5\times 5\times 5})$

$=2(\frac{27}{125})$

$=\frac{54}{125}$

$2(\frac{3}{5})^3=\frac{54}{125}$

NeX [460]

Answer:

m=-8/3

Step-by-step explanation:

1/m+4=3/4

cross multiply over the equal sign

1×4=3(m+4)

4=3m+12

combine the like terms

4-12=3m

-8=3m

divide by 3

-8/3=3m/3

m=-8/3
