Answer: 10 - 2√21
Step-by-step explanation: I simplified your question by using an online calculator. :)
The sixth graders collected $250 of their $300 goal. The seventh graders collected $250 of thier $450 goal.
Sixth Graders:
$250 / $300
Reduce: $25 / $30 = 5/6
Seventh Graders:
$250 / $450
Reduce: $25 / $45 = 5/9

Answer:
2×3^2×5^10
Step-by-step explanation:
We presume you want the simplified product ...
3^2×5^2×2×5^3×5^5
The applicable rule of exponents is ...
(a^b)(a^c) = a^(b+c)
The bases are 2, 3, 5. The exponent of 2 is 1; the exponent of 3 is 2; the exponents of 5 are 2, 3, 5, so those get added.
= 2×3^2×5^(2+3+5)
= 2×3^2×5^10
