Answer:
a) 4^6
b) 5^5
c)3^9
d)2^-2
Step-by-step explanation:
When raising a number to a power and then to another power, you can multiply the exponents.
When multiplying numbers with the same base to different exponents, you can add the exponents.
Hello
5^(2x) = 27
if : a>0 and b>0 a = b <span>equivalent to log(a) = log (b)
</span> log (5^(2x)) = log(27) ... (1)
a>0 and b>0 log(a^n) = nlog(a)
(1) equivalent to :<span>2x log 5 = log 27</span>
1.BD=AC
AC^2=(9^2)+(6^2)-2(9)(6)COS115
AC^2=117-108COS115
AC=√71.358
AC=8.447//
The answer to that is 0.80 which is f because you convert the answer like you would do normal equations
3.2128 is a rational number
