Which expression is equivalent to 4 power to 6 times 4 power to -8

Step-by-step explanation:

This is the answer because:

1) 4 to the power of 6 times 4 to the power of -8 equals to 1/16

2) is also equal to 1/16 because 4 squared equals 16, and then the fraction form is 1/16; therefore, the answer is

Hope this helps!

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
