Answer 1
Answer: Hello,

First we must find the ratio:

r= ( u_(2))/( u_(1)) = (20)/(-5) =-4\n\n r= ( u_(3))/( u_(2)) = (-80)/(20) =-4\n\n u_(1)= -5\n u_(2)= -5*(-4)\n u_(3)= -5*(-4)^2\n u_(4)= -5*(-4)^3\n \boxed{u_(n)= -5*(-4)^(n-1)\n}\n\n Answer\ B

Write these expressions in exponential form. Example: 12 to the power of 2 x 12 to the power of 6= 12 to the power of 2 +61. 11 to the power of 16 x 11 to the power of 1=

2. a to the power of 6 x a to the power of 8 =

3. (-2) to the power of 12 x (-2) to the power of 1=

4. 1.1 to the power of 7 x 1.1 to the power of 9 =

5. 3 to the power of 4 x 5 to the power of 2 =

Answers

Step-by-step explanation:

1. 11 to the power of 16 x 11 to the power of 1

  • 11^(16)*11^1=11^(16+1)=11^{17

2. a to the power of 6 x a to the power of 8

  • a^6*a^8=a^(6+8)=a^(14)

3. (-2) to the power of 12 x (-2) to the power of 1

  • (-2)^(12)*(-2)^1=(-2)^(12+1)=(-2)^(13)

4. 1.1 to the power of 7 x 1.1 to the power of 9

  • 1.1^7*1.1^9=1.1^(7+9)=1.1^(16)

5. 3 to the power of 4 x 5 to the power of 2

Assumed it is both 3 or 5, we take 3

  • 3^4*3^2=3^(4+2)=3^6

Solve for x in terms of a,b, and c: ax - 3b =c. . 1: a(c+3b). 2: a (c-3b). 3: c-3/a. 4: c+3b/a

Answers

We have to solve x in terms of a, b and c:
a x - 3 b = c
a x - 3 b + 3 b = c + 3 b
a x = c + 3 b
x = ( c + 3 b ) : a
Answer:
4 ) ( c + 3 b ) /a
