Which is the value of this expression when a=5 and k=-2

Zinaida [17]

Answer:

Option C is correct.

Step-by-step explanation:

We are given the expression:

$(\frac{3^2a^{-2}}{3a^{-1}})^k$

The value of a =5 and k = -2

Putting the values and solving

$=(\frac{3^2*5^{-2}}{3*5^{-1}})^-2\\=(\frac{3^{2-1}}{5^{-1+2}})^-2\\=(\frac{3^{1}}{5^{1}})^-2\\\\=(\frac{3}{5})^-2\\if \,\,a^{-1} \,\,then\,\, 1/a\\=\frac{(3)^{-2}}{(5)^{-2}}\\ Can\,\,be\,\,written\,\,as\\\\=\frac{(5)^{2}}{(3)^{2}} \\=\frac{25}{9}$

Option C is correct.

Step by step what is the answer to 11=12-q

Shtirlitz [24]

Your answer: q=1.

Steps:

1.) Add q to both sides. (11 + q = 12 - q + q.)

2.) Simplify. (11 + q = 12.)

3.) Subtract 11 from both sides. (11 + q - 11 = 12 - 11.)

4.) Simplify again. (q = 1.)

Hope this helped :)
