Find the value(s) of n if n^4=625.
Grace [21]
The answer is 5 and -5, because squaring a positive or negative number give the same value, so square rooting that number should give back those positive and negative value. THIS ONLY WORKS FOR WHEN THE SQUARE ROOT OR THE SQUARING IS AN EVEN NUMBER.

Show that 5 2/3 - 3 4/5 = 1 13/15
topjm [15]

Answer:

True both are 28/15

Step-by-step explanation:

Simplify the following:

5 + 2/3 - (3 + 4/5)

Put 3 + 4/5 over the common denominator 5. 3 + 4/5 = (5×3)/5 + 4/5:

5 + 2/3 - (5×3)/5 + 4/5

5×3 = 15:

5 + 2/3 - (15/5 + 4/5)

15/5 + 4/5 = (15 + 4)/5:

5 + 2/3 - (15 + 4)/5

15 + 4 = 19:

5 + 2/3 - 19/5

Put 5 + 2/3 - 19/5 over the common denominator 15. 5 + 2/3 - 19/5 = (15×5)/15 + (5×2)/15 + (3 (-19))/15:

(15×5)/15 + (5×2)/15 + (3 (-19))/15

15×5 = 75:

75/15 + (5×2)/15 + (3 (-19))/15

5×2 = 10:

75/15 + 10/15 + (3 (-19))/15

3 (-19) = -57:

75/15 + 10/15 + (-57)/15

75/15 + 10/15 - 57/15 = (75 + 10 - 57)/15:

(75 + 10 - 57)/15

| 7 | 5

+ | 1 | 0

| 8 | 5:

(85 - 57)/15

| 7 | 15

| 8 | 5

- | 5 | 7

| 2 | 8:

Answer: 28/15

______________________________________

Simplify the following:

1 + 13/15

Put 1 + 13/15 over the common denominator 15. 1 + 13/15 = 15/15 + 13/15:

15/15 + 13/15

15/15 + 13/15 = (15 + 13)/15:

(15 + 13)/15

| 1 | 5

+ | 1 | 3

| 2 | 8:

The Area of a square at right is 72 square units Find the value of X, <br>Did I do this right?
Assoli18 [71]
Yes, your work is correct.

The diagram does illustrate x²+6x+9=72.  This is also represented by

(x+3)² = 72

We can take the square root of both sides:
\sqrt{(x+3)^2}=\sqrt{72}&#10;\\&#10;\\x+3=\pm 6 \sqrt2&#10;\\&#10;\\x+3-3=\pm 6 \sqrt{2} -3&#10;\\&#10;\\x=-3\pm 6\sqrt{2}

When we evaluate this, the answers are x = -11.5 or x = 5.5.
