Answer:
After simplifying, the exponent of x is 33 and the exponent of y is 0
Step-by-step explanation:
For us to simplify, we bring the x base together and the y base together
Recall from the law of indices;
x^a/x^b = x^(a-b)
and x^a * x^b = x^(a + b)
We shall be applying these here
Let us bring the x terms together
we have these as;
x^8/x^14 * 1/x^-39 = x^( 8 - 14 -(-39))
= x^(8 + 39-14) = x^33
for y, we have it that;
y^-26/y^-5 * 1/y^-21
= y^(-26 -(-5) - (-21)
= y^-26 + 5 + 21 = y^0
Answer:
95/4
Step-by-step explanation:
Given,
a/b =2/3
Therefore, 2a²+3b²/a²+b² = ?
We get,
a/b = 2/3
So, we can write
a = 2 and b = 3
Now,
2×(2)² + 3×(3)²/(2)² + (3)² [Putting the values of a and b]
= 2×4 + 3×9/4 + 9
= 8 +27/4 + 9
= (32+27+36)/4 [ Taking L.C.M, we get 4]
= 95/4
Answer: 236 kcal
Step-by-step explanation:
Given : A serving of fish contains 50 g protein and 4 g of fat.
i.e. content of protein = 50 g
content of fat = 4 g
Also, The caloric value in protein = 4 kcal/g
The caloric value in fat = 9 kcal/g
Calories in 50 g protein = (content of protein)x (caloric value in protein )
= 50g x 4 kcal/g = 200 kcal
Calories in 4 g fat= (content of fat)x (caloric value in fat)
=4 g x 9 kcal/g = 36 kcal
Then, the total calories in the serving will be :Calories in 50 g protein + Calories in 4 g fat
= 200 kcal+ 36 kcal =236 kcal
Hence, there are 236 kcal in the serving.
