Answer:
1 2/5
Step-by-step explanation:
Step 1:
1.4 = 140/100
Step 2:
140/100 = 70/50
Step 3:
70/50 = 35/25
Step 4:
35/25 = 7/5
Step 5:
7/5 = 1 2/5
Answer:
1 2/5

(5^-2 ● 4^-4)^-2
you need to multiply tge power of tge outside the bracket with tge power inside the bracket to eliminate the power
= 5^4 ● 4^8
the answer is A
Im guessing that it is 5 but then again dont trust me XD
Use u subsitution the solve by grouping
u=x^2
u^3-16u=4u^2-64
u^3-4u^2-16u+64=0
(u^3-4u^2)+(-16u+64)=0
u^2(u-4)+(-16)(u-4)=0
(u^2-16)(u-4)=0
(u-4)(u+4)(u-4)=0
(u+4)(u-4)^2=0
u=x^2
(x^2+4)(x^2-4)^2=0
(x^2+4)((x-2)(x+2))^2=0
(x^2+4)(x-2)²(x+2)²=0
set to zero
x^2+4=0
x^2=-4
x=+/-2i
x-2=0
x=2
x+2=0
x=-2
the other roots are -2 and 2

True. because it is still 6 away from 0 no matter what way you go
