Which of the following represents sixth root of x to the fifth power in exponential form?
5x6
6x5
x to the 5 sixths power
x to the 6 fifths power

Option 3 is correct.

Step-by-step explanation:

we have to write in exponential form.

Step 1: sixth root of x can be written as

Step 2: Fifth power of sixth root of x

which implies x to the 5 sixths power.

Option 3 is correct.

see explanation

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
