Answer:
Step-by-step explanation:
When you multiple same numbers with different exponents, the exponents add. Example x^2 * x^3 = x^4
When you divide same number with different exponents, the number subtracts
1. 5^4 * 5^8 = 5^12
2. 11^18/ 11^-4 = 11^22
The answer is D
You multiply the denominator with the whole number and and the numerator
Step-by-step explanation:
49 = -16t^2 + 56t
-16t^2 + 56t -49 = 0
(-4t +7) (4t -7) = 0
-4t+7 =0
t = 7/4
