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

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

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

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

Answer:

x²-5x+6

Step-by-step explanation:

The question is to find product in : x(x-2)+3(2-x)-----------(a)

Make terms in brackets same by introducing a negative sign as;

Collect like terms as : x(x-2) - 3 (x-2)------------ (b)

Note that expression (a) is similar to (b)

Factorize equation (b) as : (x-3)(x-2)

Distribute as : x(x-2) -3 (x-2 ) ------ x²-2x-3x+6

Collect like terms as: x²-5x+6

Final expression : x²-5x+6

Testing with x=5 in original expression

x(x-2)+3(2-x)

5(5-2)+3(2-5)

25-10+6-15

25+6-10-15

31-10-15=6

Using the final expression;

x²-5x+6

5²-5(5)+6

25-25+6
