Answer:
There are many possible solutions. For example,
(2^3)^4 = ((2^5)^12)/((2^6)^8) = 2^10 x 2^2 = (2^19)/(2^7)
(2^2)^5 = ((2^6)^11)/((2^7)^8) = 2^1 x 2^9 = (2^20)/(2^10)
Step-by-step explanation:
Answer:
a = 4
b = -3
Step-by-step explanation:
Let a and b be the two numbers.
According to question,
4a - b = 19........(i)
And,
a + 4b = -8........(ii)
From (i),
4a - b = 19
or, b = 4a - 19
Replacing b in (ii),
a + 4(4a - 19) = -8
a + 16a - 76 = -8
17a = -8 + 76
17a = 68
a = 68/17
a = 4
And,
b = 4a - 19
= 4 x 4 - 19
= 16 - 19
= -3
Answer:
-5120
Step-by-step explanation:
a = 10
r = -2
Tenth term: 10(-2)⁹
= -5120
Answer:
y = -6/5x - 5.6
Step-by-step explanation:
6x + 5y = 6
-6x -6x
5y = -6x + 6
/5y /5y
y = -6/5y + b
-2 = -6/5(-3) + b
-5.6 = b
