Answer:
1/3
Step-by-step explanation:
simplify
81^(-1/4)
= 1/81^(1/4)
= 1/[3×3×3×3]^(1/4). (factorize 81)
= 1/[3]^(4/4)
= 1/3
Ok so its a guessing game
I say its 40+10 because
40-10{one # is 10 less than)=30
10(3){three times the other number}=30
so 40+10=50
Answer:
A: 4
B: -2
Step-by-step explanation:
calculate dy/dx:
A: 1 to the right and 4 up: gradient is 4/1 = 4
B: 2 to the right and 4 down: gradient is 4/-2 = -2
Step-by-step explanation:
phukan = x
Nanwan = y
let this be a simultaneous equation.
x - y = 18.... equation i
x + y = 100.... equation ii
subtract equation i from equation ii
= 2y = 118
y = 59
substitute y = 59 in equation ii to get x
x + 59 = 100
x = 100- 59
x = 41
Nanwan = 59, Phukan = 41
Answer:
3.) 10
Step-by-step explanation:
8x-2(x+1) = 7x+8
8x-2x-1=7x+8
6x-1=7x+8
-1=1x+8
+1 +1
1x+9
/x
x=1+9
x=10
