the correct ones :
7³/7² =7
2^10/2 = 2^9
Answer:
Step-by-step explanation:
If the radius, r, is given, then the area of the circle is A = πr².
If the diameter, d, is given, then the circle area is A = π(d/2)², or A = πd² / 4.
Answer: y=
s=-30+10t
Step-by-step explanation:
9x + 2y = 5; y
9x-9x+2y = 5-9x
2y=5-9x
y=
1/15s - 2/3t = -2; s
(1/15s - 2/3t = -2)*15 ==> Get rid of fraction by multiplying both sides by 15
s - 30/3 t=-30
s-10t=-30
s=-30+10t
When you write logarithm of 1 with base b = x, through logarithm properties, that would be x to the power of b equals 1.

Now, from the law of exponents, any number raised to the power of zero is 1. Thus logarithm of 1 with base b is truly zero.
