Answer:
12, 20
Step-by-step explanation:
Don't worry I just know
891
prime factors number to factorize
3 297
3 99
3 33
3 11
11 1
Therefore, the prime factorization of 891 is 1×3×3×3×3×11= 1×3^4×11, or 1*81*11
Answer is 13 because the numbers are increasing though odd numbers that are also increasing if that makes sense.
It’s going from 4 > 9 > 16 > 25 > 36
so from 4-9 it adds 5 and from 9-16 it adds 7 and goes on so that’s it’s like
+5 > +7 > +9 > +11
sorry if it doesn’t make good sense
Step-by-step explanation:
(2x³y^-4)^-2 = 1/(4x⁶y^‐8) = y⁸/(4x⁶)
1/(8x⁵y^-7) = y⁷/(8x⁵)
4x^-9y⁴ = 4y⁴/x⁹
so, the whole expression is then
y⁸/(4x⁶) × y⁷/(8x⁵) × 4y⁴/x⁹
4y¹⁹/(32x²⁰) = y¹⁹/(8x²⁰)
so, D is the correct answer.
