Answer:

Option B. m⁷/n²  is the correct answer.

Step-by-step explanation:

Identity,

xᵃ * xᵇ = xᵃ⁺ᵇ  

xᵃ/xᵇ = xᵃ⁻ᵇ

x⁻ᵃ = 1/xᵃ

It is given that,

m⁻⁶ n⁻³/m⁻¹³ n⁻¹

Using  these three identities we can write,

m⁻⁶ n⁻³/m⁻¹³ n⁻¹ = m⁻⁶ m¹³/n⁻¹n³   (since x⁻ᵃ = 1/xᵃ)

m⁻⁶ m¹³/n⁻¹n³ =m⁽⁻⁶⁺¹³⁾/n⁽⁻¹⁺³⁾ = m⁷/n²  (since xᵃ * xᵇ = xᵃ⁺ᵇ   and xᵃ/xᵇ = xᵃ⁻ᵇ)

Therefore Option B. m⁷/n² is the correct answer

Solve the following math problem and give me an example please C/-7+3.2=2.7
jasenka [17]
C/-7+3.2=2.7

Step 1) Add 7 to both sides because what you do to one side you must do to the other
         C/<u>-7</u>+3.2=<u>2.7</u>
          <u>  +7          +7
</u>          C/+3.2=9.7

Step 2) Subtract 3.2 from both side
          C/<u>+3.2</u>=<u>9.7
</u>          <u>    -3.2   -3.2
</u>              C/=6.5

Your answer is C=6.5<u>

Identify the slope of the line for the equation y = 10x + 3.
Iteru [2.4K]

Answer:324

Step-by-step explanation:

int i = 42.7;            /* konwersja z double do int */

float f = i;             /* konwersja z int do float */

double d = f;            /* konwersja z float do double */

unsigned u = i;          /* konwersja z int do unsigned int */

f = 4.2;                 /* konwersja z double do float */

i = d;                   /* konwersja z double do int */

char *str = "foo";       /* konwersja z const char* do char*  [1] */

const char *cstr = str;  /* konwersja z char* do const char* */

void *ptr = str;         /* konwersja z char* do void* */

Suppose that y varies inversely with x. Use the information to find k, and then choose the equation of variation. x = 1.2 when y
baherus [9]
Y = k/x where k is the constant of variation
y = 3 , x = 1.2 gives
3 = k/1.2
therefore 
k = 3*1.2 = 3.6
and the  required equation is 

y = 3.6 / x
