-5^9 ; (5^3)^-2 <---- Neither of these is equal to 1/(5^9)
3^5 * 3^2; 3^20/3^2 <--- Neither of these is equal to 3^10
4*x; x^-4/x^8 <---- Neither of these is (always) equal to x^4
0 <--- This is the only value not equal to 1, the value of 8^0
It’s C because it works and it should help you get it right
Answer:
14 7/12
Step-by-step explanation:
You take 6 3/4 and subtract 1/2 cup, which equals 6 1/4. Then you take 6 1/4 and divide that by 3. Then you multiply that answer (2 1/12) by seven.
12/21 in its simplest form is 4/7.
To find this out we need to divide the numerator and denominator by the GCF of 12 and 21 which is 3.
12/21
12 ÷ 3 = 4
21 ÷ 3 = 7
4/7
12/21 in its simplest form is 4/7.
12/21 = 4/7
