Question

The error in the equation

Answer 1

Answer:

I a=-3/4

Step-by-step explanation:

4-3=(42)2a

same bases

-3/4=4a/4

=-3/4

Answer 2

Answer:

a = -3/4

Step-by-step explanation:

1/64 = 16 ^(2a)

4^ -3 = 2^4 ^(2a)

4^-3  =2^(8a)

The bases are not the same so the exponents cannot be equated yet

2^2^-3 = 2 ^(8a)

2 ^ (-6) = 2 ^(8a)

Now the bases are the same so we can equate the exponents

-6 = 8a

Divide each side by 8

-6/8 =a

-3/4 =a
