4 0

Step-by-step explanation:

In order to add, subtract, multiply or divide, the order of radicals (or Surds) must be equal.

(1) ERROR IN THE SIMPLIFICATION:

Order of radicals are not made equal

(2) CORRECT SOLUTION:

\frac{ \sqrt[7]{ {x}^{5} } }{ \sqrt[4]{ {x}^{2} } } \\ \\ = \frac{ \sqrt[7 \times 4]{ {x}^{5 + 4} } }{ \sqrt[4 \times 7]{ {x}^{2 + 7} } } \\ \\ = \frac{ \sqrt[28]{ {x}^{9} } }{ \sqrt[28]{ {x}^{9} } } \\ \\ = \sqrt[28]{ \frac{ {x}^{9} }{ {x}^{9} } } \\ \\ = \sqrt[28]{ {x}^{9 - 9} } \\ \\ = \sqrt[28]{ {x}^{0} }\\\\ =\sqrt[28]{1}\\\\= 1

Answer:

There are now 6.5 ounces in the new bag.

Step-by-step explanation:

To solve this question, take 30% of 5 and add it to the original amount of 5

30% = 0.30

5 * 0.30 = 1.5

5 + 1.5 = 6.5 ounces of candy.

Select the expressions that are equivalent to 12n - 8. Select all that apply.
morpeh [17]

A.3n+4+3n+4+4n

=3n+3n+4n+4+4

=10n+8

B.11n+4+n-12

=11n+n+4-12

=12n-8

C.6(6n-2)

=36n-12

D.4(3n-2)

=12n-8

E.4n+22-12+8n

=4n+8n+22-12

=12n+10

so,B and D are the expressions that are equivalent to 12n-8.

Answer:

Commutative property of multiplication

Step-by-step explanation:

Commutative property of multiplication basically means that the order in which you multiply numbers does not matter.

For exampe:

3 x 4 = 4 x 3

    12 = 12

In your case:

5 x 7 x 4 = 5 x 4 x 7

        140 = 140

If we break that down:

5 x 7 x 4 = 5 x 4 x 7

   35 x 4 = 20 x 7

        140 = 140
