I think the answer is 2 13/20
Or, in decimals: 1.3
We have been given the expression
We have the exponent rule
Using this rule, we have
Now, using the fact that ![x^{\frac{1}{n}}=\sqrt[n]{x}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D%3D%5Csqrt%5Bn%5D%7Bx%7D)
, we get
![x^{\frac{9}{7}}= \sqrt[7]{x^9}\\ \\ x^{\frac{9}{7}}=\sqrt[7]{x^7\times x^2}\\ \\ x^{\frac{9}{7}}=x\sqrt[7]{x^2}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B9%7D%7B7%7D%7D%3D%20%5Csqrt%5B7%5D%7Bx%5E9%7D%5C%5C%0A%5C%5C%0Ax%5E%7B%5Cfrac%7B9%7D%7B7%7D%7D%3D%5Csqrt%5B7%5D%7Bx%5E7%5Ctimes%20x%5E2%7D%5C%5C%0A%5C%5C%0Ax%5E%7B%5Cfrac%7B9%7D%7B7%7D%7D%3Dx%5Csqrt%5B7%5D%7Bx%5E2%7D)
D is the correct option.
The best thing to do is to find 10%, and you can do this by dividing $270 by 10, and therefore, $27 is equal to 10%. To find 40%, you've got to multiply $27 by 4, and this gives you $108. Therefore, gabriel saved $108 last month :)
hope this helps u
As the question is written, the <em>correct answer</em> is:
19519.
Explanation:
Our question states
y = 143.3(5)² + 1823.3(5) + 6820
To evaluate this, we use the order of operations (PEMDAS). There is nothing to be evaluated in parentheses, so P is taken care of.
The E part, exponents, is 5². This is 25, which gives us:
y = 143.3(25) + 1823.3(5) + 6820
Next we have M and D, multiplication and division (in the order they appear). Our multiplication is:
143.3(25) = 3582.5; and
1823.3(5) = 9116.5.
This gives us:
y = 3582.5 + 9116.5 + 6820
Lastly, we add these:
y = 12699 + 6820
y = 19519
