Answer:
3.33×10⁴
Step-by-step explanation:
You can use the hint, or you can use a common exponent. Here is the latter case.
(3.9×10⁴) -(5.7×10³) = (3.9×10⁴) -(0.57×10⁴) = (3.9 -0.57)×10⁴
= 3.33×10⁴
_____
With a little practice, you can see the effect on exponents of moving the decimal point. Here, we have ...
5.7×10³ = (0.57×10)×10³ = 0.57×(10×10³) = 0.57×10⁴
__
When adding or subtracting in scientific notation, all that is required is that the exponents of all the numbers be the same. The hint says make all the exponents be 0. Above, we have chosen to make them all be 4. You could also use 3:
(3.9×10⁴) -(5.7×10³) = (39×10³) -(5.7×10³) = (39 -5.7)×10³
= 33.3×10³ = 3.33×10⁴
With inverse functions you just swap 'x' and 'y' and solve for 'y'.
Swap 'x' and 'y':
Add 7 to both sides:
Take the square root of both sides:
If you are asking which ratio is equivalent to 8 then it is neither. They are both simplified to 3:1. 54/18= 3, 18/6= 3. If you were asking if they were equivalent to each other the answer is yes.
Step-by-step explanation:
given,
6(p+6) - (p-6)
→ 6p + 36 - p + 6
→ 5p + 42 ans.

There are 5 because 2 divided by 2/5 is 5
do keep change flip
keep the first number
(2) change division to mulitplication and then put 5/2 and multiply
