Answer:
1/9^5
Step-by-step explanation:
![\dfrac{9^2}{9^7}=\dfrac{9\cdot 9}{9\cdot 9\cdot 9\cdot 9\cdot 9\cdot 9\cdot 9}=\dfrac{1}{9\cdot 9\cdot 9\cdot 9\cdot 9}=\boxed{\dfrac{1}{9^5}}](https://tex.z-dn.net/?f=%5Cdfrac%7B9%5E2%7D%7B9%5E7%7D%3D%5Cdfrac%7B9%5Ccdot%209%7D%7B9%5Ccdot%209%5Ccdot%209%5Ccdot%209%5Ccdot%209%5Ccdot%209%5Ccdot%209%7D%3D%5Cdfrac%7B1%7D%7B9%5Ccdot%209%5Ccdot%209%5Ccdot%209%5Ccdot%209%7D%3D%5Cboxed%7B%5Cdfrac%7B1%7D%7B9%5E5%7D%7D)

An exponent is an indicator of repeated multiplication. As you can see, factors in the numerator cancel those in the denominator, so the result is the difference of the exponents.
Answer:
p = 48
Step-by-step explanation:
If p is inversely proportional to the square of q
This is written Mathematically as:
p ∝ 1/q²
p = k × 1/q²
p = k/q²
Cross Multiply
k = pq²
k = Constant of Proportionality
Step 1
We find k
When p is 3 when q was 12
k = pq²
k = 3 × 12²
k = 432
Step 3
determine p when q is equal to 3
p = k/q²
p = 432/3²
p = 48
