Answer:

x=5/2

Step-by-step explanation:

(2/7)^2x *(2/7)=(2/7)^6

(2/7)^(2x+1)=(2/7)^6

Equate indices

2x+1=6

2x=6-1

2x=5

x=5/2

Answer:

When multiplying the same number, raised to different powers, you carry the number forward so (2/7)^6 is part of the answer.

Now, we have to calculate the exponent.

2x + 1 = 6

So, the answer is x = 2.5 which means

[2/7]^(2*2.5) x [2/7]^1 = [2/7]^6 which equals

[2/7]^5 x [2/7]^1 = [2/7]^6

Answer:

1. -6y^4 +4y^2 -12

2. x - 19

Step-by-step explanation:

(6y^4+3y^2-7) - (12y^4-y^2+5)

= -6y^4+ 4y^2- 12

2. 3(x-5) - (3x+4)

= (3x-15) - (3x+4)

= x-19
