We need a common denominator before we subtract. Both numbers go into 8. 5/8 stays as 5/8 and 1/2 becomes 4/8

Now we can subtract: 5/8 - 4/8
All we have to do is subtract the numerators (5 - 4) and keep the same denominator.

5 - 4 = 1

The answer is <span>1/8.</span>

Describe how a power with a zero exponent and a power with a negative exponent can be simplified?
Liono4ka [1.6K]
-----> A<span>ny number at all with a 0 exponent is 1; anything with a -ve exponent means "1 over" i.e. 5^-1 means 1/5, 23^-4 means 1/23^4 etc. 



</span>----->A number to the power of zero is always 1 
<span>A number to the power of a negative number such as 2^-4 is always the reciprocal to the power of 4 so 2^-4 is in fact (1/2) ^4 = 1/2^4 </span>

<span>3^-3/4 is (1/3)^3/4 </span>

<span>(4/9)^-3/5 is (9/4)^3/5
</span>

--->Any number with a zero exponent is equal to 1. A number n to the -x is equal to 1/(n^x)<span>



To simplify a negative exponent expression , I attached an example it is easier that way :)


Hope that helps.xoxo

Y is inversely proportional to d^2 When d=10 y=4 D is directly proportional to x^2 When x=2, d=24 Find a formula for y in terms
Sati [7]

Answer:

y = 1.44x⁴

Step-by-step explanation:

From the question,

Y∝d²

To remove the proportionality sign we introduce a constant.

Y = kd²............... Equation 1

make k the subject of the equation

k = Y/d²............. Equation 2

Given: Y = 4, d = 10

Substitute these values into equation 2

k = 4/10²

k = 4/100

k = 0.04

Substitute these value of k in equation 1

Y = 0.04d²................ Equation 3

Similarly,

d∝x²,

d = Cx²

make C the subject of the equation

C = d/x²................... Equation 4

Given:  d = 24, x = 2

Substitute into equation 4

C = 24/2²

C = 24/4

C = 6

Hence,

d = 6x²................... Equation 5

Substitute the value of d in equation 5 into equation 3

y = 0.04(6x²)²

y = 0.04(36x⁴)

y = 1.44x⁴

Hence the formula for y in terms of x is y = 1.44x⁴
