Find $ \left(\frac{5}{12}\right)^{4}\left(\frac{12}{15}\right)^{3} $.
vitfil [10]

Question:- Find

\left(\frac{5}{12}\right)^{4}\left(\frac{12}{15}\right)^{3}

Answer:-

\left(\frac{5}{12}\right)^{4}\left(\frac{12}{15}\right)^{3}

Taking power inside the bracket

\frac{5^{4} }{ {12}^{4} }  \times  \frac{ {12}^{3} }{ {15}^{3} }

\frac{ {5}^{4} }{ {12}^{4 - 3} }  \times  \frac{1}{ {(5 \times 3)}^{3} }  \\  \frac{ {5}^{4} }{12}  \times  \frac{1}{ {5}^{ 3 } \times  {3}^{3}  }  \\  \frac{ {5}^{4 - 3} }{12 \times  {3}^{3} }  \\  \frac{5}{4 \times 3 \times  {3}^{3} }  \\  \frac{5}{4 \times  {3}^{4} }  =  \frac{5}{4\times81 }  \\  Answer-> \frac{5}{324}

Power\:Form-> \frac{ 5 }{12 \times {3}^{3} }

The diameter of a Frisbee is 12 in. What is the area of the Frisbee?
boyakko [2]
The area of the Frisbee is 36π square inches or approximately 113.04 square inches.

Since the Frisbee is circular, its area can be solved by the equation:
A = πr^2 where r= diameter/2 = 6 in
A = 6*6π in
A = 36π square inches or approximately <span>113.04 square inches

boyakko [2]

Answer:

506

Step-by-step explanation:

Given that :

Number students admitted in 2017 = 207

Number of students admitted in 2018 = 299

To obtain the number of students admitted in both years, we use the addition operator as it is an addition problem. It requires the sum of students admitted both in 2017 and 2018

Number students admitted in 2017 + Number students admitted in 2018

207 + 299 = 506

506 students were admitted in total in both 2017 and 2018
